--- Comment #21 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Douglas Mencken from comment #20) > I'm lost. “Vanilla” 5.1.0 configured without --disable-checking went thru > stage2 w/o any issue... That's interesting - we might run into a miscompilation here. Can you check with --disable-checking again but with just the gcc_checking_assert in hash_table_mod1 removed? Please also attach preprocessed source of genmatch.c for the stage2 build so it's possible to investigate that with a cross compiler. (preprocessed source with --disable-checking and the assert left in place) Btw, thanks for your help in tracking this down. I wonder if anybody tried a powerpc-linux bootstrap with --disable-checking...
