Faust synth instant crash

[d.healey]

On Linux. Added a scriptnode synth, added a faust node, created a file, kaboom.

This is all I get in my console output. No stack trace unfortunately.

Faust: Resizing buffers: nChannels=0, blockSize=0
Combobox changed, new text: testFile
Faust DSP file to load:/home/dave/Desktop/faustTest/DspNetworks/CodeLibrary/faust/testFile.dsp
Faust jit compilation successful
Segmentation fault

@d-healey Works on macOS, please debug.

the hello world synth would be this:

// Faust Source File: dudel
// Created with HISE on 2023-03-19
import("stdfaust.lib");

freq = hslider("freq", 220.0, 20.0, 20000.0, 0.01);


process = os.oscsin(freq) , _;

Good to see @d-healey is working on FAUST synth. Hope we will learn some new FAUST technics from him. (y)

[d.healey]

I think I'm getting somewhere...

This is the line where the failure occurs: https://github.com/christophhart/HISE/blob/develop/hi_faust_jit/FaustWrapper.h#L137

Do I need to be using a particular version of faust or clang?

@d-healey Did you try the FAUST version on Windows ?

What is your FAUST synth code ?

@DabDab

Did you try the FAUST version on Windows ?

Nope, I don't care if it works on Windows or Mac :)

What is your FAUST synth code ?

Nothing, it crashes as soon as I create a file.

Here's a video:

@d-healey OK.. Got it... did you try to create FAUST as ScriptFX ? Did it work ?

Your video shows this is a bug of HISE, unable to create DSPnetworks Files.

@DabDab

did you try to create FAUST as ScriptFX ? Did it work ?

Same issue.

[DabDab]

@d-healey What FAUST version are you using ? please use 2.50.6

[d.healey]

@DabDab 2.54.9

[DabDab]

@d-healey I tried 2.54 on my mac. It didn't work. 2.50.6 has no issue so far (This kind of crashing)

[d.healey]

@DabDab Building now, I'll report back

[d.healey]

@DabDab Thanks, that solved it. @Christoph-Hart Faust version was the issue. I had to compile it manually because the version in my distro is too new.

@d-healey

Have a happy Synth design.
