Fair enough.  In any case, the symptoms are again consistent with a lack of
registration of unwind tables, this time for libgcc, so this might be the s=
ame
underlying issue as the grep-induced mess for GCC 10.  My hunch would point=
 to
a  constructor section merging issue in the linker, maybe related to the GCC
configure check for HAVE_LD_RO_RW_SECTION_MIXING, which should fail for Min=
GW
and may incorrectly succeed when things go wrong.=
