member templates and default parameter

[Stefan Seefeld <seefeld at sympatico dot ca>]

 the following code doesn't compile, even though I believe there is
nothing wrong with it.

struct Default{};

class Bar
{
public:
  template <typename T, typename P = Default>
  void foo(T t) {}
};

int main(int, char **)
{
  Bar b;
  b.foo(24);
}

bash$ g++ -c templ.cc
templ.cc:7: default argument for template parameter in function template `void 
   Bar::foo(T)'
templ.cc: In function `int main(int, char**)':
templ.cc:13: no matching function for call to `Bar::foo(int)'
bash$ 


Is this a known bug ?
