Marek Polacek <mpolacek at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution|--- |FIXED --- 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.
