------- Additional Comments From ehrhardt at mathematik dot uni-ulm dot de  2003-07-29 09:57 -------
The code is invalid. This line:

	typedef foo<A, A>::helper<1> helper_type;

must be written as

	typedef typename foo<A, A>::template helper<1> helper_type;

However, gcc should not issue an Internal Compiler Error. This is
fixed in 3.4. Note that there are two different ICEs, one if both
typename and template are are missing. There's another one if
template is there but typename is missing.

Reduced example:

template <typename , typename >
struct foo {
	template <int> struct helper { };   
};
template <typename A>
struct bar : public foo<A, A>
{ 
	typedef foo<A, A>::helper<1> helper_type;
};
bar<double> b1();
