From: "blelbach at cct dot lsu.edu" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/53446] New: Template function incorrectly rejected when convertible argument is provided for a parameter Date: Tue, 22 May 2012 05:14:00 -0000 [thread overview] Message-ID: <bug-53446-4@http.gcc.gnu.org/bugzilla/> (raw) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53446 Bug #: 53446 Summary: Template function incorrectly rejected when convertible argument is provided for a parameter Classification: Unclassified Product: gcc Version: 4.7.1 Status: UNCONFIRMED Severity: major Priority: P3 Component: c++ AssignedTo: unassigned@gcc.gnu.org ReportedBy: blelbach@cct.lsu.edu Created attachment 27471 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27471 Failing test case (Thanks to rjmccall on #llvm for explaining the details of why this is a bug) In the attached code snippet, the second parameter of f<>(), B<>, is a non-deduced context, but the first argument D<> permits the deduction of T=int. That substitution should succeed, and then the second argument is convertible. The candidate can't be rejected just because B<something> can't be matched with A.
