I've noticed an odd behaviour with the netCDF libraries v3.3 & v3.4 
compiled for DEC Alpha.

When creating a file from scratch the resulting netCDF file is fine.  If I 
subsequently add an additional variable to the file, other (pre-existing) 
variables will get scrambled.  This only occurs to some variables at some 
2-D slices.  Visually it looks like a 2-D slice has been subdivided into 
several rectangular areas then randomly put back together.  I'm guessing 
that some internal directory header is getting corrupted when the new 
variable is getting defined.  This was not a problem pre-v3.  Current libs 
work fine on the SGI.

Anyone else see this and have a fix?  I haven't tested the effect of file 
size but the ones we use are typically >100mb .

Cheers -- Jeff
