Synopsis: Explicit parameterization of templated return value fails within templated function

State-Changed-Why:
    Already fixed for 3.4. In the meantime, you can work
    around this by writing
      x.template apply<bool>();

>Description:
When compiling:

class Example
{
public:
  Example() { }
  template<typename R>
  R apply( void ) const {
     return R ();
  }
};


template <typename GCC_BUG>
void foo () {
  Example x;
  x.apply<bool>();
}

Errors:
  g++    -c -o break-gcc.o break-gcc.cpp
  break-gcc.cc: In function `void foo()':
  break-gcc.cc:15: syntax error before `>' token

Same code compiles without incident in Intel's CC, and appears (from my reading and others) to be legal standard C++.  This problem appears to occur in all GCC releases that I have tried (2.95, 3.0 and 3.2)
