--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
For testing bugs against trunk it is better to omit both --disable-checking and
--enable-checking=release and just use the default.
Because otherwise the compiler doesn't perform various verifications and you
could see a miscompilation which would otherwise be caught already at compile
time.
