Comment # 3 on bug 68391 from Vladimir Ysikov

I tray get backtrace after crash, but gdb said "No stack". Maybe it does not
crash, it's normal exit from the program?

My course of action:

1)$gdb --args Sanctuary -video_app opengl -sound_app openal -engine_config
../data/unigine.cfg -data_path ../ -extern_define RELEASE -video_fullscreen 0 
-video_mode -1 -video_width 1024 -video_height 768

2)(gdb) run

3)Wait until the closure of the program window

4)(gdb) bt
