--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Note that this first started to ICE with r223470, which is also the first
revision where it starts opening cmds-check.c (which also premature to me,
because no warning is actually emitted; I'd think that it should do that only
if the warning is actually going to be emitted and needs it, otherwise it is an
unnecessary compile time slowdown); that ICE got later fixed in r224236, but
later reappeared (in r230331).
