The answer from the netCDF FAQ (available as http://www.unidata.ucar.edu/packages/netcdf/faq.html): 12. Is there a problem with building netCDF under AIX 3.2? We have observed a problem with the optimizer in the C compiler of AIX 3.2. The default for our configure script is to specify optimization by using the "-O" compiler flag, but that causes the netCDF library to be built incorrectly under AIX 3.2, with the symptom that "make test" will fail even though there are no compile or link errors when building from source. A workaround is to build the netCDF library with CFLAGS="" (or "-g") explicitly, by setting the environment variable CFLAGS to "" or "-g" before invoking configure, or by using one of the other methods suggested in the INSTALL file to prevent the use of the "-O" flag for compilation. The specific file that is incorrectly compiled with "-O" is libsrc/string.c, so another workaround is to just compile that file without "-O". -- Russ Rew UCAR Unidata Program address@hidden P.O.
