At the end of process_filter(), collapse_tree() was changed to update the parg parameter, but the reassignment after the call wasn't removed. What happens is that the "current_op" gets modified and freed and parg is assigned to the new allocated argument. But after the call to collapse_tree(), parg is assigned again to the just freed "current_op", and this causes the tool to crash. The current_op variable must also be assigned to NULL in case of error, otherwise it will cause it to be free()ed twice.
