Internal Compiler Error egcs-1.0.1

[Gregory Bond <gnb at itga dot com dot au>]

This admittedly bizarre code causes a sigsegv.  Guess who was playing
around with nested template members?

As an aside, the standard (& comp.std.c++ newsgroup) assert
the following is legal, egcs disagrees:
	class foo {
	  template <typename T> class member_template;
	};
	template <typename T> class A::member_template {};
---------------------
The file tt2.C:
---------------------
class A
{
      class A_impl;
   public: 
      A(){}
};


template <class j> class A::A_impl
{
};
---------------------
