segfault at 18 in libc-2.19.so with VB 5.1.6

[Don Hughes]

Guest and all VBox controls totally unresponsive. Had to kill VBoxSVC from another session to regain control. CPU was NOT at 100% as in previous freezes.

A VBox.Log is attached. However, this is from after the restart. It looks like the log from the fault was overwritten.

No chance to debug this without a core dump.

I have followed the instructions in the wiki for previous bugs, but have never been able to generate dump. I am running a SUSE 13.2 system with a 3.16.7 kernel and an openBox window manager. Anything special that I need to do to enable dumps?

[Don Hughes]

Has not reoccurred with 5.1.24

Thanks for the information, I will close this ticket.
