Thanks for your bug report. This is fixed in the mainline, but
difficult to fix for gcc 2.95.1 (at least, my fix fails in your
example).

It is also a bug in your code, which is not strictly
well-formed. Still, the compiler should not crash. To work around the
problem, you can write

#include <vector>

template <class T>
class Container : private vector<T>
{
public:
  typedef typename vector<T>::value_type value_type;
  void insert(value_type);
};

(which is completely standard C++), or

#include <vector>

template <class T>
class Container : private vector<T>
{
public:
  void insert(Container::value_type);
};

(which works with gcc 2.95 as well, as an extension).

Most likely, you are missing a few typenames here and there. gcc 2.95
supports some more strictly conforming C++ programs than earlier
versions of g++. As a side effect, it also has to enforce the rules on
typename a bit more strictly - this keyword is really necessary to
disambiguate in some cases.
