Using gdb on the coredump I see:
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Core was generated by `gdm-session-worker [pam/gdm-launch-environment]'.
Program terminated with signal SIGSEGV, Segmentation fault.

[Current thread is 1 (Thread 0x7f9f513e9040 (LWP 1291))]
So is this a GDM issue, kernel or something else?
