This has become one of our Frequently Asked Questions for netCDF.  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".
