Segmentation fault

[Ghan, Steven J]

I'm trying to display netcdf history from wrf. The ncdump -h of this
file is attached.  <<wrfout_d01_0001-01-01_00_00_00.2d.ncdump>> 
I open it with xdfopen using the following ddf file 
DSET ./wrfout_d01_0001-01-01_00:00:00.2d
TITLE wrf
UNDEF 99999.0
XDEF west_east 201 LINEAR 0.0 0.25
YDEF south_north 2 LINEAR 0.0 0.1
ZDEF bottom_top 80 LINEAR .125 .250
TDEF Time 13 LINEAR 0Z1JAN01 5mn
VARS 4
T=>t 80 99 perturbation potential temperature
QVAPOR=>qvapor 80 99 water vapor mixing ratio
QCLOUD=>qcloud 80 99 cloud water  mixing ratio
QRAIN=>qrain 80 99 rain water  mixing ratio
ENDVARS

I can display a 1-d slice of any number of fields, but when I try to
display in more than one dimension (i.e., a contour plot) I can only
display once. The second display always produces a segmentation fault,
even if it is for the same field and dimensions. Any ideas what the
problem might be?

I am using gradsnc v1.8SL11 on linux redhat 7.3
