--- Comment #4 from afn2-HmMyXyqgL2CVc3sceRu5cw@public.gmane.org ---
Thanks for the reply, Ilia. The video card is a GeForce 750M (GK107) in a
mid-2014 MacBook Pro Retina.

I rebuilt the library without stripping symbols and then reproduced the crash.
Here's an updated stack trace. Luckily it doesn't appear that there are
multiple threads doing GL work:
