| It's a GCC bug. We have worked around it in recent versions of QEMU;
| what version are you trying to compile?
I'm using bisect to find a runtime behavior bug (OpenBSD/amd64 current's cd53.iso segv's in
userland) that showed up since 1.4.0 release. So understandably I'm building lots of versions
and not able to stick with current for the duration of the bisection.
| You can compile that file with "-O2 -fno-gcse".
Awesome, I'll just do a global -fno-gcse and hope that doesn't effect the runtime bug I've
encountered to speed my compile times ;-)
Thanks,
