>Description:
This short snippet:
template <class T>
class vector { };

class OUTER {

public:
  template <class T>
  class List { };

  vector<class List> data;
};

triggers an ICE:
bug.cc:4: internal error: Segmentation fault
>How-To-Repeat:
No ICE but:
bug.cc:7: `struct list' redeclared as different kind of symbol
bug.cc:5: previous declaration of `template<class T> class list'
for (e.g. no enclosing class):
template <class T>
class vector { };

template <class T>
class List { };

vector<class List> data;

Also, the new parser ICEs on the first testcase, compiles
with errors the latter. Other compilers manage to deal
without errors with both of them.
