--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
If the problematic older system gcc was 4.1+, can you please bisect among *.o
files compiled by the system gcc?
If the ICE is with the stage1 gcc when building stage1 libgcc, then
the suspected TUs could be gimple-ssa-store-merging.o or fold-const.o, would be
nice to start with those.
I.e. build again with your older system gcc, verify it fails, make a copy of
those two *.o files, rebuild them with gcc 8.x, make cc1 cc1plus and verify it
doesn't ICE anymore.
