Sorry for dropping the ball on this. I'm afraid it's hard to debug even with this information. If you could run the vm under valgrind (you need to have a valgrind that has randomization disabled - see http://spice-space.org/wiki/index.php?title=Valgrind) it would perhaps point to the culprit. Stack trace would help too, but it won't point to the problem assuming it is memory corruption. > > Regards, > TF > > > 2013/1/22 Alon Levy <al...@redhat.com>: > >> Hello All, > >> > >> while using remote-viewer, qemu and libs as compiled below, my > >> 32bit-win7-VMs (spice-guest-tools-0.3.exe) are crashing quit > >> frequently, and the following error is shown in the hosts dmesg > >> log: > >> > >> segfault at 50 ip 00007f8b6bab3119 sp 00007f8b64db3b00 error 6 in > >> libspice-server.so.1.6.0[7f8b6ba70000+11b000] > > > > Can you install debug information and provide a stack trace?
