[Wrf-users] segmentation fault with grib2 data

[nilima natoo]

Dear wrf_users,

While using ./ungrib.exe I came across with following error message for
grib2 type data:
[nma at k6 WPS]$ ./ungrib.exe
  *** Starting program ungrib.exe ***
Start_date =  1979-01-01_00:00:00 ,      End_date = 1979-01-01_00:00:00
output format is WPS
Path to intermediate files is ./
 ungrib - grib edition num           2
Segmentation fault


This kind of segmentation problem does not occur with grib1 type data.
In addition to that there is no 'Error' message while compilation and all
executables are created.

This is how ungrib specific portion of my namelist.wps looks like:
&share
 wrf_core = 'ARW',
 max_dom = 1,
 start_date = '1979-01-01_00:00:00',
 end_date   = '1979-01-01_00:00:00',
 interval_seconds = 21600
 io_form_geogrid = 2,

&ungrib
 out_format = 'WPS',
 prefix = 'FILE',


I am using NCEP-CFSR grib2 data and Vtable.CFSR looks like this
