State-Changed-When: Tue Feb 15 17:08:27 1994
State-Changed-Why:
This seems to be a Gawk bug.  

We are not running the most recent version of Gawk, but running the
same test with the current version on a SunOS 4.1.1 system makes me
think that upgrading will not solve our problems.

	conklin@ngai$ gawk '' 
	gawk: cmd. line:1: fatal error: internal error

The only difference is the core dump.  I'll see if upgrading gets rid
of the core dump, but right now it looks like the gawk maintainers
should be made aware of the bug.

State-Changed-When: Wed Feb 16 17:24:38 1994
State-Changed-Why:
I've contacted the gawk maintainers about this bug.  I've been told that
the bug has been fixed, and that they expect to make another release 
shortly.  There is nothing we can do until the next release.

State-Changed-Why:
integrated gawk 2.15.5, which fixes this bug.
