I've got the same issue on my system with /usr/lib/dri/iris_dri.so crashing instead of radeonsi_dri.so.

Same problem here when run xonotic (radeonsi_dri.so).

Change in PKGBUILD:

-D b_lto=true

to:

-D b_lto=false

Then recompile, and not crashing anymore.

Patched gcc is in testing; new testing/mesa 20.2 will be up in a bit.
