[netCDF #PMD-881681]: Segementation fault in netcdf-fortran parallel test

Subject: [netCDF #PMD-881681]: Segementation fault in netcdf-fortran parallel test
Date: Fri, 22 Feb 2013 14:44:25 -0700
Looking more closely at the HDF5-1.9.10-patch1 release notes, I cut and pasted 
the
wrong entry, as that was just the addition of a couple of new functions and 
unlikely
to fix anything.  So, never mind ...
