  "message": "Avoid is_constructible recursion in OnceAction\n\nBoth OnceAction compatibility traits, IsDirectlyCompatible and\nIsCompatibleAfterIgnoringArguments, check std::is_constructible before\nis_callable_r.\n\nOn libc++ that order breaks. Evaluating\nis_constructible\u003cstd::tuple\u003cOnceAction\u0026\u0026\u003e, ...\u003e drives libc++\u0027s tuple\nconstructor SFINAE, which calls back into OnceAction\u0027s converting\nconstructor and re-enters the conjunction while it is still incomplete.\nGCC \u003c\u003d 8 (e.g. QNX 7.1\u0027s gcc 8.3) rejects this with:\n\n    incomplete type ... used in nested name specifier\n\nso EXPECT_CALL(m, f()).WillOnce(Return(...)) fails to compile. GCC \u003e\u003d 9\nand every Clang accept the original order; libstdc++ is unaffected.\n\nSwapping the two checks fixes it: is_callable_r is cheap and\nnon-recursive, so the conjunction short-circuits to false for the\nnon-callable tuple before is_constructible is instantiated.\n\nFixes #3947.\n",
