egcs-1.1.2 interal compiler error (template problem)

[Paul Burchard <burchard at math dot ucla dot edu>]

In egcs-1.1.2, the following (ill-formed) C++ program generates an
"interal compiler error":

        template<class T> class x { class y : public T {} _y; };
        int main() { x<int> _x; }

Here are the specs on my environment:
