ham/dpbox debugging help?

[Chris Maness <christopher.maness%gmail.com@localhost>]

Backstory: wanted to get ham radio (packet/AX.25) running on NetBSD.
I knew nothing about TNT/DPBOX/TFKISS combo.  Got it running save for
DPBOX crashing when a new user tries to set their home BBS.  Reading
up on DPBOX, it is supposed to be 100% solid production grade
software, so I am thinking code rot, or it always had this bug.  To
test the factuality of the statement "100% stable and ready for
production", I got it running on Slackware 11 (the latest Slackware it
will compile/run on).  It is in fact very stable/mature, and found TNT
to be an excellent packet radio terminal.  Something worthy of a nice
NetBSD box.  TNT and TFKISS seem to be ok -- no bugs that I can tell.

Here we are:
Now have the thing running with debugging symbols on board, but gdb
dpbox does not behave the way I am used to.  It detaches instead of
staying attached.

Therefore tried:
 gdb -p 6247

Ok, seems to work, but when I trigger the crash, nothing happens, and
ps aux tells me:

The process is TXs (zombie?), but no core dump or anything useful on GDB.

If someone is willing to play with it, I can send them a VirtualBox
install of DOS 6.22 running a packet terminal that they could use to
connect with it with a TCP master/slave TTY link between another
virtual box running NetBSD.

Caveat emptor:

I know enough to be dangerous, but definitely a n00b to fixing these
things and NetBSD.
