[netCDF #PVO-840684]: Question About Make Check In netcdf4.1.1

Hi Tony,

Sorry to have taken so long to respond to your question.  We're short-handed 
due to vacations, and have a growing backlog of support questions, with only
two developers available and an oversubscribed list of commitments.  I was 
actually looking at your question when your "SECOND ATTEMPT" email arrived.

We haven't been able to duplicate the problem here, but that may be because
our only AIX platform is an old powerpc-ibm-aix5.1.0.0, on which we still
haven't installed HDF5-1.8.5.  We haven't seen the problem you reported on
any other of our testing platforms.

We run different tests than the HDF5 tests, so it's not surprising that we
could get different results.  The problem you reported is a symptom of getting
an error return from the HDF5 call in libsrc4/tst_h_files.c

  if (H5Dwrite(datasetid, native_typeid, mem_spaceid, file_spaceid, 
xfer_plistid, bufr) < 0) ERR;

so my next step would be to rebuild with HDF5 detailed logging turned on by 
configuring with --enable-logging and making an initial call to set the HDF5
logging level to get more detail by calling


sometime before the error occurs.  That will tell what HDF5 error is actually
occurring.  Or you could see it by using a debugger to descend into the HDF5
level calls.  The person who would usually do this won't be back until Aug 13, 
but I'll try to investigate further before then ...
