Please file a separate bug report about the integer overflow. It's a different
bug, and I don't maintain AI code.

Follow-up Comment #1, bug #25538 (project wesnoth):

The division by zero is intenational there.

The integer overflow might not be though, maybe we should change that ai code
to use floats instead.
