A shot in the dark, but can anyone point me in the right direction? Thought this might be similar to this bug (http://cygwin.1069669.n5.nabble.com/1-9-2-0-Xwin-SIGSEGV-when-font-server-should-be-queried-td65322.html), but it's years old, and my build is the latest.

Thanks.

Figured it out. Turns out I had an older version of my "Intel HD graphics" driver. Updating to the latest solved this problem.

I saw "ati" in the backtrace and figured it might be a driver issue. A good guess.
