From: bangerth@dealii.org To: gcc-bugs@gcc.gnu.org, gcc-prs@gcc.gnu.org, martin@xemacs.org, nobody@gcc.gnu.org Subject: Re: c++/9437: template function parameter `T*' shouldn't match pointers to members Date: Fri, 24 Jan 2003 20:12:00 -0000 [thread overview] Message-ID: <20030124201259.22766.qmail@sources.redhat.com> (raw) Synopsis: template function parameter `T*' shouldn't match pointers to members State-Changed-From-To: open->analyzed State-Changed-By: bangerth State-Changed-When: Fri Jan 24 20:12:59 2003 State-Changed-Why: Something's indeed wrong here. To see what the template parameter matches, execute the following variation: ------------------------- extern "C" void printf (const char *, ...); struct S { template <typename T> operator T* () const { printf ("%s\n", __PRETTY_FUNCTION__); return static_cast<T*> (0); } } null; struct A { int i; }; static void f (int A::* pmi) { } int main () { f (null); } ----------------------------- It displays g/a> /home/bangerth/bin/gcc-3.4-pre/bin/c++ x.cc g/a> ./a.out S::operator T*() const [with T = int A::*] But then the return type would be _pointer_ to member pointer, not member pointer. Confirmed with 2.95, 3.2.2, 3.3, 3.4 W. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=9437
