--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Another test:
enum class error {};
template <typename F>
void afunction(F) {
error{char(0)};
}
93513.C: In function ‘void afunction(F)’:
93513.C:4:16: internal compiler error: unexpected expression ‘(char)(0)’ of
kind cast_expr
4 | error{char(0)};
