Hello,

The following lines of code cause my IDL session (linux, 8.3 and 8.4) to segfault. Do the gurus have any advice for my novice NCDF skills?

Cheers!

A





d = NCDF_CREATE( './test.nc', /CLOBBER, /NETCDF4_FORMAT )


theGroup = NCDF_GROUPDEF( d, 'groupname' )


theTitle = NCDF_VARDEF( theGroup, 'my_title' )


;; Segfault happens here, but ONLY when the /STRING keyword is set.
NCDF_ATTPUT, theGroup, theTitle, 'my_title', "blah blah blah", /STRING

Yes, upgrade to IDL 8.4.1. :-) This bug was just fixed.
8.4.1 should be going up on the web site in a couple of weeks.

Another piece of advice: don't use the netCDF STRING data type unless you really want it. It can't be read by Fortran programs. Use the old CHAR data type.
