Hi all,

I gave Linux 2.6.36-rc1-git4 a try today coming from 2.6.35.3.

Once in a while X crashes with an SIGBUS in pixman (0.18.4) [see the backtrace
attached].
I'm filing this bug here because it 'seems' that this is somehow connected
to the Kernel version as I was not able to reproduce this with 2.6.35.3.

I cannot provide a definite way to reproduce this issue. It happened during
different actions such as flickering through a PDF document and resizing an
mplayer window.

Keep up the excellent work!
