I think since the upgrade to GCC 9.2 in Fedora, the glibc test
nptl/tst-cancelx18 (which is built with -fexceptions) fails on the Arm
32-bit architecture (and only there). 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

Upon second thought, this must be something else, unrelated to the GCC
9.2 update.
Thanks,
