I'm not 100% certain that it's caused by the GCC update, but the patterns of failures and passes strongly suggests that. I don't know the proper name for the exact 32-bit Arm variant Fedora uses. Its armv7 with hardware floating point, I think. I'm trying to get a lab machine to debug this further, but in the past, that was difficult. Thanks, Florian
