Interesting. My run reported 1 failure but make check is quite verbose
so it was hard to tell which. However there was a core in the
directory:

Of course it may be wedged as X has been up and down while I've been
generating bug traces for Jesse:

https://bugs.freedesktop.org/show_bug.cgi?id=21480

However it caught my eye as the crash in libdrm there was due to a bad
pointer somewhere between bo_gem and bucket.

I assume the kernel side should be resilient to user space crashes
though?
