GDB Backtrace for the GTK port when running the perft test Speedometer/Full.html (debug built on r182181)

Finally I was able to get the test crash with the Debug build. However, the trace I got seems different than the one from the release build. So maybe we are hitting here another bug.

In any case, I'm attaching here the GDB backtrace. The relevant part is:

Program terminated with signal SIGSEGV, Segmentation fault.

The following output was also printed on the screen:
