Exceptions while evaluating xqueries with Qexo

[Daniel Aborg <lists dot kawa at daborg dot fastmail dot fm>]

Hi,

I'm getting two rather odd exceptions when evaluating some of our 
XQueries using Qexo, both seem to be related to the bytecode compiling.

If anyone has any idea what might be causing the problem based on the 
exceptions below I'd love the input. I'll also try to isolate the cause 
and see if that makes things more clear.

Thanks,

Daniel
