[LDM #VLF-828955]: ldm-6.11.5 pqinsert problems

Julie & Stephen,

We'll, I guess I don't know what's causing the pqinsert problem, then. As I 
indicated,  I didn't have any problem. 

The SIGSEGV problem will be fixed in the next release.  For the moment,  the 
workaround is not to use an invalid option.
