--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 45671 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45671&action=edit gcc9-pr89285-wip.patch Updated version that handles the above mentioned C++ stmt trees. That said, there are still various regressions: /usr/src/gcc/obj/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/vector.tcc:636:48: in 'constexpr' expansion of 'std::vector<int, std::allocator<int> >::_S_use_relocate()' /usr/src/gcc/obj/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/vector.tcc:636:8: error: modification of '#'result_decl' not supported by dump_expr#<expression error>' is not a constant expression etc.
