From: "f.heckenbach@fh-soft.de" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/104577] New: needs copy constructor to call method of class non-type template parameter Date: Thu, 17 Feb 2022 03:55:49 +0000 [thread overview] Message-ID: <bug-104577-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104577 Bug ID: 104577 Summary: needs copy constructor to call method of class non-type template parameter Product: gcc Version: 11.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: f.heckenbach@fh-soft.de Target Milestone: --- % cat test.cpp struct S { constexpr S () = default; S (S &&) = delete; operator int () const { return 0; } }; template <S s> int i = s; int main () { return i <S { }>; } % g++ -std=c++20 test.cpp test.cpp:8:20: error: use of deleted function 'constexpr S::S(const S&)' test.cpp:1:8: note: 'constexpr S::S(const S&)' is implicitly declared as deleted because 'S' declares a move constructor or move assignment operator I don't see why a copy constructor should be needed here. (clang accepts it.)
