This was reported before; for even more information see our ticket:

Stock gcc 4.3 compiles freeciv fine even with -O2 (at least that is true on
my system). I suspect that certain distros have added patches to their
gcc which are now causing certain code to be miscompiled. -O1 fixes it,
but it is possible that disabling just the optimizations caused by the custom
patches would also fix the problem.
