The latter could happen if you are trying to open a netCDF-4 file or a netCDF-4 classic model file with a program linked to a netCDF library that was built without the --enable-netCDF-4 configure flag. So, for example, if someone provided a file that makes use of netCDF-4 compression features in a netCDF-4 classic model file and you try to open the file with a netCDF-3 library or a netCDF-4 library built without the --enable-netcdf-4 flag or built without access to an HDF5 library (needed for netCDF-4 features), then you would get that error. It would also occur if you try to rid a text file or any other non-netCDF file when a netCDF file is expected. --Russ > forrtl: severe (174): SIGSEGV, segmentation fault occurred > > Image PC Routine Line > Source > > libc.so.6 00000031F7478F50 Unknown Unknown > Unknown > > ccsm.exe 000000000123AC53 Unknown Unknown > Unknown > > ccsm.exe 000000000112C693 Unknown Unknown > Unknown > > ccsm.exe 00000000010EB834 Unknown Unknown > Unknown > > ccsm.exe 000000000114C7FC Unknown Unknown > Unknown > > ccsm.exe 00000000010E5265 Unknown Unknown > Unknown > > ccsm.exe 0000000000B43C96 ice_pio_mp_ice_pi 213 > ice_pio.F90 > > ccsm.exe 0000000000B5B3D8 ice_restart_mp_re 1122 > ice_restart.F90 > > ccsm.exe 0000000000BC5925 cice_initmod_mp_c 138 > CICE_InitMod.F90 > > ccsm.exe 0000000000AD6EC2 ice_comp_mct_mp_i 218 > ice_comp_mct.F90 > > ccsm.exe 00000000004B4960 MAIN__ 686 > ccsm_driver.F90 > > ccsm.exe 00000000004AC32C Unknown Unknown > Unknown > > libc.so.6 00000031F741D974 Unknown Unknown > Unknown > > ccsm.exe 00000000004AC239 Unknown Unknown > Unknown > > > Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: IDQ-812680 Department: Support netCDF Priority: Normal Status: Closed
