>Description:
When I try to compile a certain C++ program under NetBSD-current, g++
exits with an internal error.  This happens only with the gcc 2.95.3
based compiler that comes with -current; neither gcc 2.91 (in an earlier
NetBSD-current), gcc 2.96 (which comes with a certain other operating
system), nor Comeau C++ (a commercial third-party compiler) has any
problem compiling this code.

>How-To-Repeat:

Execute the shell commands

  cat >test.cc <<EOF
  int t(char *, char *);
  template <class K>
  struct H {
	  typedef int t;
  };
  template <class K>
  struct X {
	  typedef H<K>::t t;
	  void g(t);
  };
  EOF
  cc -c test.cc

and see the error message

  test.cc:9: Internal compiler error 61.
  test.cc:9: Please submit a full bug report.
  test.cc:9: See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

>Fix:

Upgrade to gcc 2.96 or newer.
