Hi Barron,

> 
> Conceptual steps to reproduce the problem:
> 1. Create a NETCDF4 formatted file
> 2. Define coordinate variable dimension
> 3. Define another dimension
> 4. Define a non-coordinate variable
> 5. End definition mode
> 6. Reopen definition mode
> 7. Define a coordinate variable sharing the dimension name from step 2
> 8. (optional) write data
> 
> Expected result: File with two dimensions and two variables, each
> variable having a different dimension.
> Actual result: File with two dimensions that, according to ncdump,

Thanks for reporting the problem.  We have verified it and also determined that
it's not platform-specific.  We'll let you know when we have a fix.
