File header is inconsistent among processes

[Wei-keng Liao]

Hi, Sean

This error means the metadata (dimension names, variable names, variable's dimensions,
attributes, and whatever will be stored in the file header) is inconsistent among all
MPI processes.

Starting from 1.5.0, users can set the environment variable PNETCDF_SAFE_MODE to 1
to enable the internal checking for header consistency. So, by doing that
you might get additional information about what metadata is inconsistent.

I’m still waiting on the user for something that I need to reproduce the error and start experimenting but was hoping that someone on this mailing list might have some useful information or hints about what’s causing this error and how I might fix it (or where I might look). All of the “make check” test pass. Thanks for any input.
