From: "fweimer at redhat dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/101747] New: Two-argument version of attribute malloc does not perform overload resolution Date: Tue, 03 Aug 2021 11:49:38 +0000 [thread overview] Message-ID: <bug-101747-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101747 Bug ID: 101747 Summary: Two-argument version of attribute malloc does not perform overload resolution Product: gcc Version: 11.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: fweimer at redhat dot com Target Milestone: --- This: struct T1; struct T2; void close(T1*); void close(T2*); T1* open(const char *) __attribute__ ((__malloc__ (close, 1))); results in: t.cc:7:62: error: ‘malloc’ attribute argument 1 is ambiguous 7 | T1* open(const char *) __attribute__ ((__malloc__ (close, 1))); | ^ t.cc:7:62: note: use a cast to the expected type to disambiguate This can be observed when building RawTherapee with glibc 2.34: https://github.com/Beep6581/RawTherapee/issues/6324 Performing overload resolution in this context seems useful, given that the exact type of the argument should be known at this point (the return type of the function). I'm not sure if should add the cast to the glibc sources to work around this.
