 Confirmed with CVS from 2002-11-10. The present error message is somewhat annoying, since it repeats the same 
 text twice:
 tmp/g> /home/bangerth/bin/gcc-3.3x-pre/bin/c++ -c x.cc
 x.cc:16: sorry, unimplemented: sorry, not implemented: use of `ptrmem_cst' in
    template type unification

 Very good, I took a quick look but got lost in the macro jungle too 
 quickly and did not have my laser macro sword (== plenty of free time) 
 with me, so left it to others :-)
 
 Thanks

 I think I have an idea of where that repeatition is coming from.
 Expect a patch to correct that annoyance in a moment.

>Description:
Gcc emits the following error message when I compile the code in the 'How-To-Repeat' section.

t.cc:16: sorry, not implemented: use of `ptrmem_cst' in template type 
   unification
t.cc: In function `void f()':
t.cc:16: warning: unused variable `bar<baz, &baz::the_foo_, baz> i'
>How-To-Repeat:
Compiling the following code with 'gcc -c <filename>' will repeat the problem.

template<typename Element, int Element::*Foo, typename CVElement>
struct bar {

  bar() {}

  template<typename CVE>
  bar(const bar<Element, Foo, CVE>& x) {}
};

struct baz {
  int		the_foo_;
};

void f()
{
  bar<baz, &baz::the_foo_, baz> i = bar<baz, &baz::the_foo_, baz>();
}
