Package: gcc-12-alpha-linux-gnu
Version: 12.2.0-1cross3
Severity: normal
Starting this version of gcc, -mbuild-constants option causes it to produce
an ICE. Example is below. This is an old code, always worked before, in
particular with gcc-11.
Removing -mbuild-constants fixes the ICE. But this is a bios/firmware code,
and this option is used for purpose. Tho I don't know how important it
really is.
I tried to submit this bug upstream, but failed at the bugzilla registration
step.
