Subject: Another fatal signal in g++-2.2.2

Hi,
	Here's another file which causes a fatal error.  It is
somewhat longer than the last one I sent you.  Sample compilation:

mahogany% g++-2.2.2 -g  -c Stream.ii -o test.out
/usr/sww/bin/gcc-2.2.2: Internal compiler error: program cc1plus got fatal signal 6
mahogany%

	Hope these examples are informative,

		Vance
