Patrick Palka <ppalka at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ppalka at gcc dot gnu.org --- Comment #8 from Patrick Palka <ppalka at gcc dot gnu.org> --- FWIW I noticed that if we remove the 'constexpr' from aa27::aa27() in the reduced testcase then the ICE starts with r9-2103-g686dca7612a8ab before which we accepted the code with -std=c++2a.
