--- 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.
