Primitive Error

Questions
1

Hello,

I am running SC on RPi 4. A python script is controlling the whole synth by sending OSC.
The code is intended to run on an sound installation which means it should operate non stop.

During testing I am getting the following error in SC post window after many hours of normal operation.
The python side keeps working…

Any ideas?

ERROR: Primitive ‘_QObject_New’ failed.

That’s definitely some kind of memory allocation bug caught exception ‘std::bad_alloc’. I think you should report it on github. But since it’ hard to repro… probably there won’t be a fix soon. Try to include a backtrace (from a core dump) in your report.

I believe this is a known issue with MainMenu, which is fixed in 3.10.2 or so. Do you have the latest version of SuperCollider?

Here’s a discussion about the issue: https://github.com/supercollider/supercollider/issues/4268

Thank you @jpburstrom,

indeed I hade the 3.10 version which I installed from apt. Maybe a good time to update the apt with the latest version?

I have compiled the latest version from source and testing it now on both a RPi3 and RPi4. So far it seems all is good.

Regards
