>Description:
The following snippet triggers an ICE on the mainline:

----------------------------------
template <typename> 
struct A 
{
    struct B 
    {};
};

template <typename T> 
void func(A<T>::B* )
{
}

int main() 
{
   func<void>(0);
}
----------------------------------
regr3.cpp:9: error: variable or field `func' declared void
regr3.cpp:9: error: template declaration of `int func'
regr3.cpp:9: error: expected primary-expression
regr3.cpp:10: error: expected `;'
regr3.cpp: In function `int main()':
regr3.cpp:15: internal compiler error: in cp_parser_template_id, at cp/parser.c:8013
Please submit a full bug report,


The code is illegal (it's missing a typename), but the compiler should not ICE anyway. Moreover, the error message is _very_ confusing.
>How-To-Repeat:

>Fix:
Fix the code adding a typename in front of A<T>::B.
