We also have such a problem.

Since idl5.2 using ncdf_open and ncdf_close the same failure occure with
all of our IBM aix systems.

If I use ncdf_open /ncdf_close and a device or window command I got the
segmentation fault core dump error.

Not always at the same "ii" but it never reaches 2000.

PRO ncdf_error
; one of the following three commands gives a segmentation fault
widget_control,default_font='-adobe-helvetica-medium-r-norma l--12-*-*-*-*-60-*-*'

device,decomposed=0
window,0,xsize=100,ysize=100,color=256
FOR ii=0,2000 DO BEGIN
PRINT,ii
file_name = 'ncdf_error.nc'
cdfid = NCDF_OPEN(file_name,/NOWRITE) ; OPEN the file
NCDF_CLOSE,cdfid
ENDFOR
END

WinNT or Linux did not have this problem!

This failure is known since summer of this year by RSI, but it isn't
resolved. It has a high priority I was told.

Somone of us tries using the netCDF 3.4 library instead of the build in
2.4 by call_external.
The same result - segmentation fault.

I don't know myself if it's a problem by the IBM C-Compiler or how IDL
embedds external linked programs for
aix.
