Add a\npoison pill overload to chrono::__detail where the __parsable and\noperator>>(basic_istream&, _Parser) are defined. This ensures that when\nthey use from_stream unqualified ordinary lookup finds the poison pill,\nwhich is deleted, so a usable overload resolution result can only be\nfound by ADL.\n\nWe already have the std/time/parse/parse.cc test checking that ADL\nworks, so this doesn't add a new test.\n\nlibstdc++-v3/ChangeLog:\n\n\t* include/bits/chrono_io.h (chrono::__detail::from_stream): Add\n\tdeleted function as poison pill for unqualified lookup.\n---\n libstdc++-v3/include/bits/chrono_io.h | 4 ++++\n 1 file changed, 4 insertions(+)", "diff": "diff --git a/libstdc++-v3/include/bits/chrono_io.h b/libstdc++-v3/include/bits/chrono_io.h\nindex 8c026586d4c9..c16b555df290 100644\n--- a/libstdc++-v3/include/bits/chrono_io.h\n+++ b/libstdc++-v3/include/bits/chrono_io.h\n@@ -3115,6 +3115,10 @@ namespace __detail\n \n namespace __detail\n {\n+ // _GLIBCXX_RESOLVE_LIB_DEFECTS\n+ // 3956. chrono::parse uses from_stream as a customization point\n+ void from_stream() = delete;\n+\n template<typename _Parsable, typename _CharT,\n \t typename _Traits = std::char_traits<_CharT>,\n \t typename... _OptArgs>\n", "prefixes": [ "v1", "1/1" ] }
