[Qemu-devel] Seg Faults from 0.5.4

[Qemu-devel] Seg Faults from 0.5.4

[Michael Jennings]

I can't seem to get qemu or qemu-fast to boot properly.  The latter
hangs using up gobs of CPU, and the former seg faults.

Any ideas?  I've tried a number of boot images, including the
linux-test and freedos images from the qemu site.  All do the same
thing.

Thanks,

I only asked because I get the same problems on only one machine, but its 
amd64. It's fine for me on all x86 boxen, so I don't think I can help in 
this case.

not convinced that this is the reason, but I'd try
with a 3.3 or 3.4 gcc as 3.2.x had some issues with
the optimization ...

The optimization of the qemu code as it's compiled?  I built using
"-O2 -march=pentium" if that makes a difference...should I try -O0 or
-O1 instead?  Perhaps build for a different architecture?

Unfortunately I don't have gcc 3.4 packaged quite yet, but I should
within the next week or so.

Thanks!
Michael
