--- Comment #2 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #1) > Try to preprocess with -fdirectives-only, and compile the result as > *.cpp/*.C rather than *.ii? If that triggers the ICE, you could attach the > result here, and/or reduce. Thanks. Unfortunately -fdirectives-only doesn't help.
