--- Comment #15 from Petr <kobalicek.petr at gmail dot com> --- Unfortunately GCC doesn't report any issues even with `-Wstrict-aliasing=1`. BTW now I know I must use the may_alias attribute to my satisfaction, and this is what I'm gonna do, however, from user perspective I'm not really happy as GCC does something very silently. Personally, I would be happier if my code doesn't compile at all than having it compiled with bugs.
