Bug#691107: atanks: Game crashes when changing options

[Jesse Smith]

I have had reports of a similar problem on Fedora 17 as well. However,
on openSUSE, Ubuntu and FreeBSD they don't seem to have this problem. I
suspect there is an issue due to different build options or libraries,
that is, some new versions of tools in the build chain cause a memory
corruption, but older versions do not. That would explain why Sid and
Fedora have the problem and other distributions do not.

I've been looking at trying to find the cause (and a fix), but haven't
been able to find what causes the memory corruption which results in the
crash.

Anyone who runs into this bug, please install the debug libraries for
Atanks and run the game using the gdb debugger.

gdb atanks
> r

And, when the game crashes, please post the output of the backtrace
using GDB's "bt" command.


Thank you.
