Description of problem:
I get a segfault while running a 32-bit non-PAE Fedora 11 Preview guest on a Fedora 11 Preview host. The guest is running CTCS stress test. I was able to reproduce it 3 times. It takes about 2 hours until the guest process dies.

Version-Release number of selected component (if applicable):
kernel-2.6.29.1-102.fc11.x86_64
qemu-common-0.10-16.fc11.x86_64
qemu-debuginfo-0.10-16.fc11.x86_64
qemu-kvm-0.10-16.fc11.x86_64
qemu-kvm-tools-0.10-16.fc11.x86_64
qemu-system-x86-0.10-16.fc11.x86_64

Guest flags:
-name 002-CTCS -k de -monitor pty -vnc :1 -usbdevice tablet -m 1280 -smp 3 -hda /xen/images/fedora_11_preview_32b_qcow.img -hdb /xen/images/002.img -serial file:/tmp/guest2.fifo -net nic,model=e1000 -net tap,ifname=tap1

How reproducible:
Takes about 2 hours to reproduce.

Additional info:
Just an unqualified guess, but it's probably this issue...

Thanks Frank, this is a dup of bug #497170

We'll either cherry-pick the fix into a qemu update soon, or if upstream releases 0.10.3 we'll jump to that
