[netCDF #WJF-305473]: ncgen fails to handle output of ncdump

Hi Michael,

The first thing that's wrong is that one of your enumeration labels contains
a blank-space in its name, which ncdump doesn't properly escape:

  byte enum equilibriumStatusType {Converged = 1, Vacuum = 2, NotConverged = 3, 
      Fatal error = 4} ;

The ncdump utility should output this as

  byte enum equilibriumStatusType {Converged = 1, Vacuum = 2, NotConverged = 3, 
      Fatal\ error = 4} ;

instead, so that's a bug in ncdump.  If you manually edit the CDL file to
the second form, ncgen gets further, but ultimately exits with a memory fault.

I'll fix the bug in ncdump before the next release and pass the ncgen bug to
the developer for further investigation.

Thanks for reporting the bug!
