Well that is good.

Unfortunately I can't think of what to do for this problem without some way of 
duplicating the problem. You can tell the IDL people that if they can reduce 
the problem to a C program that calls netCDF, I would be happy to look at it.

I don't even have a copy of IDL, so I can't try and IDL code out for you. If 
the IDL people want to give a copy to the netCDF team, we can see if that helps 
us debug these problems (but no guarantees - we are a very small, community 
supported free software project, without the resources to support much support 
effort. But we will try.)

Please let us know if you learn any more about this.

Thanks,

Ed
