Then cxx_eval_call_expression returned the s initializer, and my empty base overhaul in r13-160 got confused because the type of init is not an empty class. But that's OK, we should be checking the type of the original LHS instead. We also want to use initialized_type in the condition, in case init is an AGGR_INIT_EXPR. I spent quite a while working on more complex solutions before coming back to this simple one. PR c++/105622 gcc/cp/ChangeLog: * constexpr.cc (cxx_eval_store_expression): Adjust assert. Use initialized_type. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/no_unique_address14.C: New test.
