  "message": "c++: constexpr prvalues vs genericize [PR120502]\n\nHere constexpr evaluation was getting confused by the result of\nsplit_nonconstant_init, which leaves an INIT_EXPR from an empty CONSTRUCTOR\nto be followed by member initialization.  As a result\nCONSTRUCTOR_NO_CLEARING was set for the time_zone, and\ncxx_eval_store_expression didn\u0027t set it again for the initial clobber in the\nbasic_string constructor, so when cxx_fold_indirect_ref wants to check\nwhether the anonymous union active member had type non_trivial_if, we see\nthat we don\u0027t currently have a value for the anonymous union, try to add\none, and fail.\n\nSo let\u0027s do constexpr evaluation before split_nonconstant_init.\n\n\tPR c++/120502\n\ngcc/cp/ChangeLog:\n\n\t* cp-gimplify.cc (cp_fold_r) [TARGET_EXPR]: Do constexpr evaluation\n\tbefore genericize.\n\t* constexpr.cc (cxx_eval_store_expression): Add comment.\n\ngcc/testsuite/ChangeLog:\n\n\t* g++.dg/cpp2a/constexpr-prvalue2.C: New test.\n",
