@mzryz: Can you provide a backtrace from the core dump (assuming one was generated)?

Hi Aaron, for some reason my system isn't providing a core dump. It's a sysv lubuntu. I made sure apport and gdb are installed and enabled. No core inside the build dir or in /proc/kernel etc. Not sure why.

Most likely the same as #81334 (due to the SIGILL).

Also, you might want to update to a more modern Linux distribution for 32-bit PowerPC: https://cdimage.debian.org/cdimage/ports/snapshots/2021-04-17/

Regression was introduced by 0328e69

See #81334

That's okay, the issue has been fixed in the meantime. #85807 ;)
