>Description:
x.cpp: In method `int (* X::bar())()':
x.cpp:7: Internal compiler error.
x.cpp:7: Please submit a full bug report.
x.cpp:7: See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

Both static non-templated member, templated function
can be a callback, but their combination cannot.
>How-To-Repeat:
class X {
	template< int N >
	static int foo( ) { return N; }
public:
	typedef int (*Function)( );
	Function bar( ) {
		return foo< 5 >;
	}
};

int main( ) {
	X x;
	x.bar( )( );
	return 0;
}
