Comment 22 for bug 86072

As I feared rebuilding everything didn't help; I still get the crash when switching as happens to #12. However I can't get a proper backtrace; after rebuilding without fomit-frame-pointer and with debug enabled and crashing while switching, the Xorg log still only shows

(II) AIGLX: Suspending AIGLX clients for VT switch

Trying to debug via gdb didn't work neither; when attaching to the server it hangs it with error 0xffffe410 in __kernel_vsyscall () and backtrace

#0 0xffffe410 in __kernel_vsyscall ()

#1 0x48e7118d in ___newselect_nocancel () from /lib/libc.so.6

#4 0x08074c65 in main (argc=9, argv=0xafcf5834, envp=0x0) at main.c:452

I guess that is a problem of my own system, but I accept any suggestions to get a proper bt. I'll attach a full gdb log of this non-completely-related crash though, and wait for further news.
