--- Comment #2 from Sam James <sam at gentoo dot org> --- (In reply to Sam James from comment #0) > The issue was originally observed on a native s390 machine > (s390-ibm-linux-gnu) but I ended up minimising the ICE using cvise via > cross. I hit the issue when building squashfs-tools-4.5. It does not occur > with -march=native. > There aren't that many differences between -march=z10 and -march=native seemingly, but it appears -mzarch triggers it.
