--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Read https://gcc.gnu.org/bugs/ . The simple answer is add -save-temps to the comannd line which is failing and that should give you a preprocessed source. The other option you could try is -freport-bug and that will output a line which says please attach a file to the bug report, that file and compress it and attach that compressed file.
