Same warning here with gcc v4.4.7 in Gentoo too.

Commit 1abde923ee3cbdcce69b72d223fb0c487b892b6e by Daniel seem to not fix
the warning.
I know QA Gentoo complains about it, may exhibit random runtime failures.
We can live with it :) just a compiler warning. It compiles fine. (it's a
matter of disabling strict_aliasing in Makefile (-O2 implies
-fstrict-aliasing)).

Can you provide more information about what
compiler (name,
version) are

Sure.
