While the issue has been resolved in isl 0.26-3,
which was uploaded to unstable on 2023-06-19,
nothing has been done for the stable release,
and Debian 12.1 still comes with a "miscompiled" isl 0.25-1,
and thus gcc is still somewhat unusable(*) on older hardware(**)
This occasionally manifests as spurious failures
on e.g. https://build.opensuse.org/
* As long as no graphite optimizations are enabled it's perfectly usable.
** Older than the one on which it was built,
roughly anything pre-Ryzen / pre-Haswell.
