--- Comment #11 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- Object files are no use to us. We need preprocessed source along with analysis of what you think has gone wrong (my program crashes or prints the wrong number is rarely enough). Also, please make sure that you have compiled with all warnings enabled and that any relevant warnings have been fixed. See https://gcc.gnu.org/bugs/ for more details about what we need.
