Comment 3 for bug 373121

I've seen this before but I'm not sure where the bug is. I guess there has to be a bug in the kernel or in xorg because a userspace program is not supposed to be able to crash the system like that.

If I run it just now on my machine with intel G45 chipset I get this:
lseek(3, 73728, SEEK_SET) = 73728
close(3) = 0
munmap(0x7f7bcbd23000, 4096) = 0
