[gradsusr] Segmentation fault using wrf data

[Jeff Duda]

I would check to see if your script variable _analysis is being properly
assigned.  If it is being given a non-time value, that could indirectly
cause the segmentation fault.

Also you have an error in this line:
'draw string 7.5 8.0' _analysis

Put a space between 8.0 and the single quote (i.e., 'draw string 7.5 8.0 '
_analysis)

I see other oddities in your code, but nothing that would seem to outright
cause a segmentation fault.  You might want to check the validity of the
data by just plainly displaying the co field without running your script.
Just open grads, open your control file, and 'd co' at a few vertical
levels and time slices to see if the data exists and is okay.
