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: Jan 18 23:22:24 mbp systemd-coredump[23240]: Process 23187 (gnome-shell) of user 1000 dumped core.
