[gembud] GDRADR Segmentation fault

Dear GEMPAK Users,

I'm attempting to create a radar mosaic/composite on my WRF model forecast 
domain, and I have not yet been successful with this undertaking.  At first, I 
considered using nex2img or nex2gini to take Level III radar products from NCDC 
and mosaic them.  However, I would like to be able to create a multi-panel 
display of forecast reflectivitiy and observed reflectivity in a single GIF 

So, I switched to GDRADR, which looks to be the program I want to use.  So far, 
I have 2 radar sites and it appears that I have set up all the environmental 
variables correctly.  I have the archived base reflectivity data with the 
following naming convention:  $RAD/NIDS/%SID%/%PROD%/%PROD%_YYYYMMDD_HHMM

where %SID% is the station ID of the radar site, and %PROD% is the product 
name, in my case "N0R".

When I try to run GDRADR, I consistently receive a Segmentation fault.  I've 
tried both setting up the grid parameters and setting a CPYFIL -- both the same 
result.   Does anyone have a recommendation for me?

My parameter settings are given below.

Many thanks,
