Update of bug #13711 (project wesnoth):
Status: None => Wont Fix
Open/Closed: Open => Closed

Follow-up Comment #1:
As far as I know, there are no bugs in Wesnoth, at least not this one. So I
will close this report. If you still want to report it, please submit it to
GCC and/or SDL.
Indeed, the bug is actually in SDL, which is explicitly breaking aliasing
rules in SDLNet_Read/Write. Fortunately, Wesnoth doesn't do anything else
with the buffers; so, unless there is a severe bug in the compiler, this
can't lead to generating a broken binary.
As for GCC, the bug (or feature, since it is just the compiler being overly
careful) is fixed in 4.5, I think. Rather than disabling strict aliasing, you
should perhaps try to disable warnings about strict aliasing, or simply
configuring Wesnoth in non-strict mode. The engine is already sufficiently
slow as it is, no need to make it worse by disabling optimizations.
