Quit anyway? (y or n) y

[smoge]

I don't think is api mismatch, I recompiled sc3-plugins and it works on scsynth

[mossheim]

that's a segfault all right... the fact that it is crashing in the load_plugin routine is suspicious. I hope i didn't accidentally do anything to cause that. @smoge can you try removing UIUGens_supernova.so from your library paths and see if you get this same issue? If so it's probably my code.

[mossheim]

Hm, actually, it looks like this might be a dupe of this issue: https://github.com/supercollider/supercollider/issues/968

Trace looks pretty much the same.

[smoge]

I can try a git bisectlater to find the bad commit, when I have the time

[mossheim]

@smoge this time it's loading UIUGens_supernova.so.bak, can you remove that too?

[smoge]

Yes, I removed this one and the one in /usr/lib, now supernova boots normally

[mossheim]

ok great, that's a huge help!

[smoge]

any news on that?

[mossheim]

no, sorry - i just got back to school and swamped with work now.

[mossheim]

@smoge - have you had a chance to bisect it? i probably won't have time in the next few weeks, school has gotten really busy as november break approaches.

I understood you got it. I don't have that much time in my hands either, but I will try!

I tried to find the commit that introduced the problem.

The earliest I managed to build (with GCC7) was 3.7.0. That still has the issue for me.

My gdb stacktrace only mentions libjack and libpthread, but not supernova itself.

I also noticed that when using jack2, the problem doesn't happen, so at least there's a temporary workaround.

So I suspect that the change that triggered the issue happened in jack 1, but that's as far as I managed to push right now.

Hello @smoge @capocasa, there were some updates to supernova since this was reported Is it still an issue?

[capocasa]

Confirmed working, thank you very much!
