Crash on MacOS in compiled plugin when working with HardcodedEnvelopeModulator

Orvillain

I'm getting this on MacOS Sequoia 15.5 and all DAWs.

This is the most basic example I can come up with.
Here is the project snippet.

Make sure to compile DSP networks. Then re-load HISE and compile the project to create a VST3.

The script does this:

const var HardcodedEnvelopeModulator1 = Synth.getSlotFX("HardcodedEnvelopeModulator1");
HardcodedEnvelopeModulator1.setEffect("ScriptEnvNetwork");

Essentially what we have is:

Global modulator container
Hardcoded envelope modulator - with a ScriptEnvNetwork loaded into it (consisting of an oscillator, sig2mod, and peak node) compiled to 1 channel (mod sources need 1 channel from what I can tell)
Waveform generator
Matrix Modulator assigned to pitch of the waveform generator.

The interface script sets the HardcodedEnvelopeModulator to the correct network by using the setEffect() method.

The HISE project works fine on Windows and MacOS. The plugin will compile on Windows and MacOS.

But on MacOS, the plugin will crash the host on plugin instantiation. Seems to be a null pointer or dangling pointer issue. The crash does not occur on Windows, from what I can tell.

@Christoph-Hart

Orvillain

Is anyone else able to reproduce this on MacOS? Just curious if it is a me thing or not. I can't think why it would be mind you.

Orvillain

@Christoph-Hart Did you get a chance to look at this?

Christoph Hart

This post is deleted!

Christoph Hart

@Orvillain just checked, I couldn't reproduce the crash:

which host are you using? Can you reproduce this with the minimal JUCE audio plugin host?
Does it crash when running under a debugger? If yes, then giving me the location will get us to 80% of solving that.
Can you post the exact script node network? I'm plugging the modules you mentioned there, but no crash (also as a side node you don't need the peak node, the modulation signal is being calculated as the audio signal).

I'll check it out. I've debugged HISE standalone, but not yet debugged a plugin inside a host, so will need to go and figure that out.

Goodflow

@Orvillain I think someone here mentioned debugging plugins as standalone apps; I can't find the exact post but the steps are

Export > Export as Standalone App, then close the terminal window/cancel the process.
Open the generated Xcode project /Binaries/Builds/MacOSX/(PROJECT).xcodeproj
Compile/debug

I can't get your snippet to crash with a osc-sig2mod-peak node, but I'm getting the crash reliably with hardcoded fx and am pretty sure it's the same root issue.

This snippet uses a scriptFX and needs HISE_NUM_SCRIPTNODE_FX_MODS=1 or more in the project's extra definitions. On compile+debug, it'll throw JUCE Assertion failure in juce_SmoothedValue.h:301 scriptFXstacktrace.txt

If you compile and replace the scriptFX with a HardcodedMasterFX, it'll throw JUCE Assertion failure in ModulatorChain.cpp:2023 on compile+debug. Same error occurs with a polyphonic instance. hardcodedFXstacktrace.txt

I noticed the modulation chain processes in the stack traces and figured our crashes were related.

Orvillain

@Goodflow Thanks for responding!!

@Christoph-Hart

This is my network.

I am recompiling and re-exporting the plugin now. Will see if it crashes.

Here's a link to the project, in case it helps.

I'm gonna investigate how to get it debugged.

Orvillain

@Goodflow Your snippet does not crash for me. I think these are different issues.

Orvillain

Hmmm, I don't understand.

My 'blankplugin debug.vst3' file doesn't show in Ableton Live. But it did show in Reaper, and it loaded and worked.

My regular exported from HISE directly blankplugin.vst3 file does show in Ableton Live, but crashes it, and does not show in Reaper - presumably because it crashes validation.

If I build blankplugin.vst3 directly in xcode, then it won't pass validation in any host.

Orvillain

So far little success in debugging. But here's the Live crashed thread:

I suppose it isn't terribly useful, but pasting here anyway.

Orvillain

If I unload my hardcoded network, and comment out the .setEffect() call that sets it, then it does not crash.

I don't get this behaviour on Windows again by the way - that nework, whether I need various elements of it or not, compiles fine and runs in the DAW fine.

If I leave the realtime script node modulator in, instead of a hardcoded, and compile the plugin, the plugin does not crash, but the network does not seem active either - I guess it gets unloaded when compiling?? Never been 100% clear on the expectation there, I've typically just tried to compile my networks as soon as possible.

Orvillain

If I remove the Peak node in my network and compile, I get this:

It seemed previously that my network needed 1 channel to be able to be used as a global modulator. Is that correct?

I will try compiling with 2 channels, although it is saying it is expecting -1 lol - why?!

Christoph Hart

@Orvillain yes, modulators are monophonic signal generators so they need to compiled with NumChannels==1. -1 indicates that something else went wrong, but it's hard to guess from here.

Oh and I would recommend to check out a better host for testing than a full DAW (unless you specifically need to debug a certain bug that only occurs there), as this vastly accelerates the debug cycle. Check out the JUCE plugin host - you might have to build it with the VST3 SDK from source, but this is a really minimal host that you can directly launch from Xcode and if you save the plugin setup within the host, it will automatically restore it whenever you launch Xcode.

I suppose it isn't terribly useful, but pasting here anyway.

Looks like a release build without symbols, so yeah not much to gain from this.

@Christoph-Hart I have the JUCE minimal host, but whenever I add this test plugin to it, it crashes on scan. No useful log out of it.

How do I build a debug version of my plugin? Open the xcode project and change the run target to debug? There isn't a way to do one from inside HISE directly is there?

Orvillain

Right. So I emptied my Scriptnode network. Completely. Just a blank network. Compiled it. 1 channel. Re-launched HISE. Re-exported my plugin with the hardcoded network loaded as a global modulator.

Still crashes. I don't think it is to do with the contents of the network. Just the fact I have a hardcoded script envelope modulator in the global modulators altogether.

If I remove the Matrix Modulator on the waveform generator, but keep the global modulator (again, hardcoded envelope, but the network has nothing in it) and it still crashes.

At this point, I can only assume it is a configuration issue, or a HISE specific crash that I'm not describing well enough for you to reproduce it, Christoph.

Only other thing I can think is if you take my dropbox project above, compile the network in HISE on your Mac, and export the plugin your side and see if it crashes ???

The moment I remove the global modulator hardcodedenvelope instance, the plugin will load in any host.

I opened the blankplugin xcode project. Set the scheme to debug. Compiled the plugin. I get blankplugin debug.vst3 out at the end, as well as blankplugin debug.a library file. Copy the plugin to the plugins folder, make sure the old one is no longer there.

It shows up in the DAW, and it does not crash.

Sooooo... debug version not crashing.... release version... crashing. That I don't understand.

Orvillain

Yeah man, this is wild AF. The debug version works fine - even the hardcoded global envelope modulator is working.

There's something skwicky with my release build. Maybe I compiled HISE with a flag or setting, set incorrectly....???

Orvillain

Turning off link-time optimization in the xcode project seems to stop the crash from happening. It was originally set to 'Monolithic' for release, and turned off for 'debug' so that explains why debug was working and release was not.

I'm trying to build a release version with symbol support so I can see what the heck is going on.
