Xorg crashed with SIGABRT in raise()

[SZALAY Attila]

New Gigabyte motherboard, Z68 chipset, Core i5 integrated graphics, using development release which applies a bunch of updates every day, tried 3.2.0-rc* generic kernels from distribution, and built my own with same results.
I think there are too many possibilities to tell which code or hw does not work.
On m$ win there is no problem.
