--- Comment #7 from Patrick Palka <ppalka at gcc dot gnu.org> --- As in PR94597, I think the testcases here in #c0 and #c2 might be invalid as-is -- the requirement "t.cend;" should probably be "t.cend();", and we reject the former since r10-7554. With that minor change we successfully compile the reduced testcase, but we still get the same ICE with the original testcase.
