Subject: 2.3.3 - bad syntax in derived template constr arglist
Organization: GNUs Not Usenet
Distribution: gnu
Date: Wed, 30 Dec 1992 03:57:30 GMT

The code that appears at the end of this message uses templates and
derivation and contains a syntax error; some combination of that
creates an internal compiler error.

The architecture is sparc, sunos4.1.2.  The G++ is 2.3.3, as
distributed.

The verbose compiler output is:
