[Groff] Run time memory error in TBL.

[Doug Royer]

While testing my code to add cell line point-size to tables
I ran into the following memory error using Sun's DBX with
memory checking. It looks legitimate.

Does anyone know about this?

And FYI - My code seems to be working and I'll be testing it next week.
Followed by a patch to the list for comments/corrections.

This is in (TBL) main.cc. The line numbers may be off
because of my changes. I temporally commented out the
libgroff 'new' and it gets the same error so the problem
is not in 'new' as reported.

 Here is the run time error
