>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>();
}
