Hi Yakui.

I created a simple standalone test application that can reproduce
crashing very easily for my setup. Letting it run for about a minute
(13000 iterations) will run into the crash.
I posted the application source as an attachment to a bug I just
filed: https://bugs.freedesktop.org/attachment.cgi?id=110316

Here is the bug: https://bugs.freedesktop.org/show_bug.cgi?id=86913

Hope this helps to narrow it down.

Please let me know if there's more I can do to help.

Br,
