--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
4.6 seems to optimize it away too, 4.4 does not.  Anyway, strictly speaking the
code is invalid, the standard does not allow conversions between data and
function pointers I believe.  I'd say the asm barrier in the code would be
best.
