To distinguish between the two cases, it looks like it suffices to just check CONSTRUCTOR_MUTABLE_POSION in cxx_eval_component_reference before deciding to reject a DECL_MUTABLE_P member access. PR c++/92505 gcc/cp/ChangeLog: * constexpr.cc (cxx_eval_component_reference): Check non_constant_p sooner. In C++14 or later, reject a DECL_MUTABLE_P member access only if CONSTRUCTOR_MUTABLE_POISION is also set. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/constexpr-mutable3.C: New test. * g++.dg/cpp1y/constexpr-mutable1.C: New test. ^ permalink raw reply [flat|nested] 5+ messages in thread
