Great! But...the LDM still shouldn't do that.

Turns out it was an old queue and deuling pq commands. Stopping with ldmadmin, 
recreating the queue, and restarting, solved the problem.

Hi John,

While it shouldn't do that, what is the size of the queue?

Subject: [ldm-users] pqinsert and pqcheck segfaults

I'm now getting seg faults on both an older build and a fresh compile of LDM 
(6.13.5 and 6.12.14).

This all worked before I had to rebuild my system from scratch (Ubuntu 16.04 
LTS)

All compilation and configuration seems to work fine.

Output of gdb:

Reading symbols from ./pqcheck...done.
