I have a feeling there is more than one C implementation of the XDR 
standard available on the 'net - perhaps trying an alternative one might 
be something to try, in case there's a bug in the version we're using. We 
already had undetectable (for a long time) problems caused by the current 
version needing to be compiled statically.

I'd like to try this too if I had time but am unfortunately really busy 
right now.
