--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
gcc has the -fcompare-debug option, which compiles twice, once with -g and once
with -g -gtoggle and compares result, anything that fails with that option with
an error about debug vs. non-debug differences or potential differences is a
bug.
