I am having a problem running the "mini-inews" on a Convex C2 machine.
I am using version 1.5.7 (as is my NNTP server machine).  I have tried
earlier versions, and they have problems with the Convex as well.  Of
course when I compiled and ran it on a VAX 4.3BSD using the same
options as I set up on the Convex, it worked just fine.  On the Convex 
if I execute the "mini-inews" under the dbx look-a-like debugger of
Convex, it works as it should...but on the command line--it dumps core.

I am hoping that this is a configuration problem, but it does seem
strange that it would work under debugger control, but not otherwise.
Probably the brain-damaged Convex (mostly 4.3BSD) UNIX!  If you can
help me in any way, I would appreciate it.  Hoping this will help:
I am including my "conf.h" file and a short script of the debugging session.
I have tried to compile first with "CFLAGS= -O -g" and then with
"CFLAGS= -g -DDEBUG" but to no avail.  BTW, I *did* add "-ldbm" to
the link command in the Makefile because I have #define'd DBM.
