[Bug c++/13306] New: compilation error when trying to instantiate a template member function of a template class in another template function

[ydi at bam-us dot com]

I encountered this problem with GCC 3.3.2 on a Redhat 8.0 platform, as well as
with GCC 3.3.1 on Cygwin running on Windows 2000.

When I try to compile the following code:

template <class X>
class A {
public:
	template <class Y>
	void g() {}
};

template<class T>
void f() {
	A<int> a;
	a.g<double>();
}

The compiler will report "parse error before '>' token" on the line
"a.g<double>()". 

An interesting thing is that if I substitute that line with "a.f<double>()",
although there is no member function called "f" in class "A", the compiler will
accept it as long as the template function "f" is not instantiated. 

The above code is accepted by Visual C++ 2003.

The problem is that GCC has a bug in it, you can workaround it with something like this:
        a.template g<double>();
Note this is a dup of bug 795 which is fixed for 3.4.

*** This bug has been marked as a duplicate of 795 ***
