[vbox-dev] OSE VNC Crash

[Howard Su]

I got the following crash (segment fault) when I am using VboxHeadless with
VNC. It crashes during reboot of guest XP os.

I captured the core file and crash stack is following:

(gdb) where

Any idea? I suspend this is due to thread sync when vbox is switching
IFramebuffer.
