This could be related to a problem I have written some as yet private
code for, but I'm not sure that I understand you right. Do you pass
the casted pointer to user space (into a variable of the Octave
interpreter)?  Is it the problem to pass the pointer from one octfile
to another? If you have only one pointer per Octave session and only
one octfile which needs it I would see no problem ...
