I have reduced the problem reported in c++/3791, but GnatsWeb won't let me edit the existing report (sorry).

etest.cpp:11: Internal error #19990331.

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.
>How-To-Repeat:
template <class T, class U>
struct x
{
    template <class V> struct y {};
};

template <class T, class U, class V>
struct xy
{
    typedef /* typename */ x<T,U>::template y<V> y;
    y yy;
};

void f() { xy<int,char,void*> x_y; }

>Fix:
uncommenting "typename" above makes the program conforming and prevents the internal compiler error
