The code generated by htoclean for xclose is not correct. The update of
the result is missing after the call to c. This will happen for all
functions that yield just the World, but not if the result is a tuple
containing the World.

You can download a fixed htoclean.exe at:

Or instead, you could fix the generated interface by adding:
 fill_a 0 1
 pop_a 1
after the ccall for xclose in the generated .icl file.

Kind regards,
