Bug#949980: libgl1-mesa-dri: SIGSEGV in rockchip_dri.so when running Gnome/GTK
Well, I have a stack trace, but it was *shockingly* flaky to try to get
and so I don't have huge faith that it's actually correct. Guess
debugging X11 is a little more involved than "attach gdb, type
'backtrace'".
Trace attached.
Continuing.
Thread 1 "Xorg" received signal SIGSEGV, Segmentation fault.
