Bug#691107: Crash update

[Jesse Smith]

Follow up on this bug, I have discovered something interesting.

Atomic Tanks compiles and runs with no problems if it is built using GCC
4.6. However, if I switch to using GCC 4.7 (specifically 4.7.2) then the
game's memory becomes corrupted and it either displays random symbols on
the Options screen or it crashes.

I've tried compiling Atanks with the Clang compiler instead of GCC and
found that the game runs fine when built using Clang.

Since this bug only appears when the game is built with a specific
version of a specific compiler (gcc), I think that indicates there may
be a bug in the 4.7.x branch of the GNU C++ compiler.

Anyone have any thoughts on dealing with this?
