The above message contained the following:

This bug was reported earlier.  The relevant line had been changed to

    if(present(dimids)) dimids(:numDimensions) = dimensionIDs(:numDimensions)

I like your additional check on the size of the user's vector, however.
So we'll also include that in the next release.

Thanks for sending this in.
