--- Comment #1 from Sergei Trofimovich <slyfox at gcc dot gnu.org> --- Created attachment 55330 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55330&action=edit mont.c.c.orig.xz In case I reduced it too much mont.c.c.orig.xz is the original preprocessed file. ICEs with identical compiler options.
