Bug#715654: [Mayhem] Bug report on atanks: atanks crashes with exit status 139

[Alexandre Rebert]

After glancing at the code, it seems atanks crashes when init_game_settings
returns NULL. This function returns NULL if allegro could not be
initialized. Its return value will be dereferenced in atanks.cpp:5393 or
atanks.cpp:5409, and the program will crash.

I hope this helps.

Thanks,
Alex
