Created attachment 2037550 [details]
preprocessed sources
minimal command to reproduce the issue is
/usr/libexec/gcc/s390x-redhat-linux/14/cc1plus -O2 -ffloat-store -march=z13 PerspectiveTransform.i
with gcc-14.1.1-5.fc40.s390x
and it looks to me the condition to expose the ICE is -O2 AND -ffloat-store AND -march >= z13

Doesn't ICE on the trunk.
https://gcc.gnu.org/r15-1129 aka https://gcc.gnu.org/pipermail/gcc-patches/2024-June/654028.html fixed this on the trunk (but hasn't been backported yet). Note, there is https://gcc.gnu.org/r15-1344 follow-up needed for it and the question what to do with the test on s390 in case testing is done on pre-z14 hw. *** Bug 2293207 has been marked as a duplicate of this bug. *** zxing-cpp builds again with gcc-14.1.1-6.fc41, see https://koji.fedoraproject.org/koji/taskinfo?taskID=119394297 This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle.
