From: "ro at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/101747] Two-argument version of attribute malloc does not perform overload resolution Date: Thu, 17 Nov 2022 10:23:30 +0000 [thread overview] Message-ID: <bug-101747-4-3gQPeSHmu0@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-101747-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101747 Rainer Orth <ro at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ro at gcc dot gnu.org --- Comment #2 from Rainer Orth <ro at gcc dot gnu.org> --- I've recently run into what seems to be the same issue, cf. GDB PR build/29791 for details: all of gdbsupport fails to compile with gcc 12.2.0 on Solaris like this: In file included from /usr/include/sys/time.h:448, from ../gnulib/import/sys/time.h:39, from /usr/include/sys/select.h:27, from ../gnulib/import/sys/select.h:36, from /usr/include/sys/types.h:665, from ../gnulib/import/sys/types.h:39, from ../gnulib/import/stdio.h:58, from /vol/src/gnu/gdb/hg/master/dist/gdbsupport/common-defs.h:86, from /vol/src/gnu/gdb/hg/master/dist/gdbsupport/ptid.cc:20: ../gnulib/config.h:1693:72: error: ‘malloc’ attribute argument 1 is ambiguous 1693 | # define _GL_ATTRIBUTE_DEALLOC(f, i) __attribute__ ((__malloc__ (f, i))) | ^ ../gnulib/config.h:1693:72: note: use a cast to the expected type to disambiguate ../gnulib/config.h:1693:72: error: ‘malloc’ attribute argument 1 is ambiguous The preprocessed testcase (not reduced) is attached to that PR: https://sourceware.org/bugzilla/show_bug.cgi?id=29791 Unfortunately, nobody has been able to determine yet where exactly the ambiguity lies, and unlike other cases, g++ doesn't show that. Any suggestions on how to proceed?
