Crash in Cubase 9
-
Hi all,
Running into a very consistent crash with a few of my customers running Cubase 9. I managed to reproduce the issue on my rig with a symbolicated crash log and it seems to be related to switching presets and the sample loading thread. I can't reproduce it in Cubase 9.5 or higher, so it seems specific to Cubase 9. Any leads would be greatly appreciated. Here's the crash report:

Thank you!

Does it happen with other HISE based plugins too?

@d-healey I've had reports of crashes during switching presets on my plugin, various DAWs.

@DanH That's a different issue, this only happens in Cubase 9
-
@d-healey Do you happen to have any sample projects I could test?

@Casey-Kolb Happy to send mine if it helps.... Or there's the super organ collab?
-
@Casey-Kolb I'll pm you.
@DanH The organ doesn't use samples
-
Alright, so I've finally narrowed this issue down to this commit in HISE. If I revert this commit and rebuild the VST, it doesn't crash in Cubase 9.
@Christoph-Hart This was the commit you added for CUBE to fix the orb drag automation bug, so that calling
.changed()writes automation to the DAW. Any ideas as to why this might be breaking Cubase 9, but not Cubase 9.5 and above? -
Nice catch! No idea why it breaks that particular cubase version. Have you attached a debugger to cubase with a debug build yet?
-
@Christoph-Hart I have not, but that's a good call! I need to figure out how to do that first
-
@Christoph-Hart Here's an update! This is where it gets caught in Cubase 9 with that commit.
-
@Casey-Kolb Any news about this Cubase 9 problem?
-
@marcLab We're still investigating it, but should have a fix within the next week or two! Unfortunately it's a pretty deep one.
-
@Casey-Kolb One of my friends is having a strange problem with Cubase 10.5. Some presets are making the app crash. That's the message he's getting.
Tried it on my PC with the same Cubase version and I can't recreate the bug. Everything is working perfectly on my side... not a single crash. Do you think this could be related to the problem you are having on your side?
-
@marcLab Hmm, it's hard to say without seeing a crash report or debugging on that machine. My guess would be that it's unrelated because we're only having issues on Cubase 9 on Mac, but everything works perfectly in Cubase 9.5 and above. It's related to updating the automation states of various knobs when preset switching.
