>Description:
	The following program is accepted, even though operator double<int>
	is not a valid conversion-function-id (as double is not a template).

#include <stdio.h>

template <class T> struct A {
    template <class U> operator U() { return sizeof(U); }
};


int main() {
  A<double> a;
  int x = a.A<double>::operator int();
  double y = a.A<double>::operator double();
  int z = a.A<double>::operator double<int>();
  printf("%d %f %d\n", x, y, z);
}

>How-To-Repeat:
	Compile the above program.
>Fix:
	Work-around: don't use the construct.
