--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It is indeed a non-sensical combination, but I think last time we've determined
it isn't that easy to diagnose and/or silently fix up, the toplev.c diagnostics
can be bypassed through optimize attribute.
A quick hack out of this would be to add !flag_rounding_math to
can_reassociate_p next to flag_associative_math.
