Internal compiler error

[Erkki Seppala]

Code: (*.cc-file)

template <class T> struct Bar { };
template <class T> struct Foo {
  struct Baz;
};

template <class T>
struct Foo<T>::Baz :
  public Bar<T> {
};

Produced *.ii-file is essentially the same.

Problem:

Command

  gcc -v --save-temps gccbug.cc

produces

The obvious workaround is to move the definition to the actual
header file, but this creates a dependency.
