System: Linux mustikkakukko.cs.tut.fi 2.4.3 #14 Thu May 10 20:32:55 EEST 2001 i686 unknown
Architecture: i686

>Description:
	Compiling the following (syntactically incorrect) program gives
	a segmentation fault and an internal compiler error.
>How-To-Repeat:
	Here's the problematic file:
------
template<typename T, unsigned int N>
class Vector
{
public:
  template<unsigned int I>
  class Vector<T,N>::CommaInit
  {
  };
};
------
Which causes the following behaviour:
