Since r11-557, we pass the yet-uninstantiated class type S<0> of the PARM_DECL s to is_really_empty_class -- because of the potential_rvalue_constant_expression -> is_rvalue_constant_expression change in cp_parser_constant_expression. Here we're not parsing a template so we did not check COMPLETE_TYPE_P as we should. It should work to complete the type before checking COMPLETE_TYPE_P. PR c++/110106 gcc/cp/ChangeLog: * constexpr.cc (potential_constant_expression_1): Try to comple= te the type when !processing_template_decl. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/noexcept80.C: New test.
