Hi.
From the little testing i've done it seems that switching the xorg
server alone to -O2 is enough.
I'm not a fan of "dark magic" scenarios, however it seems to be a
recurring problem, at least for ARM & MIPS, doesn't seem to be the case
for x86_64.
I could make a couple test configs to see on which combinations it's
failing by extending the Qemu ones, but it's probably more hassle than
anything since there seems to be a wide spectrum of gcc versions affected.
Going for -O2 might be the quickest solution, at least for xorg-server
itself.
Regards.
