First thing to look for is which of the 3 recursive calls to
substitute_object_recurse are taken?

The next question is where in the problematic file are we reading when
the infinite recursion happens?  This could be easier to establish
starting at read_internal_start in frame 203820 (where you can see
what is 'stream').
