Instead of using the old 3.6.3 distribution, could you please try the new version 4.1.1-rc2 (without specifying --enable-netcdf-4 to the configure script) to see if it fixes the problem with AIX? I think it may be a problem with a free() call to a NULL pointer returned by a previous malloc(0) that is fixed in this release candidate version. The release is available here: ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-4.1.1-rc2.tar.gz If you build without specifying --enable-netcdf-4, it will just build and test the netCDF-3 version of the software. --Russ Thanks Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: AVS-844020 Department: Support netCDF Priority: Urgent Status: Closed
