--- Comment #9 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Unfortunately backporting is proving to be difficult.  nontype-class28.C ICEs
without r273597.  That was backported to 9 in r273597, but the
build_converted_constant_expr_internal bit is different.  Tweaking GCC 9 so
that it doesn't copy a class in a template breaks everything.

I'm too nervous about messing with that now.  So closing.
