Hey @mrkn
When I run your command in IRB console that uses ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]
I get the following segmentation fault

@kammerer I understand the inconvenience that a Python object referred from Ruby isn't freed when leaving the scope. The reason is Ruby's mark-and-sweep GC.
Currently, you can use PyCall::PyPtr.decref class method for this case. Let pyobj is a PyCall::PyObjectWrapper object you want to force deallocate, you can do it by:
PyCall::PyPtr.decref(pyobj.__pyptr__)After calling PyCall::PyPtr.decref for the PyCall::PyPtr object that has refcnt==2, the address the PyCall::PyPtr object indicates changes to 0 (NULL).
[1] pry(main)> po = PyCall.eval('object()')
=> <object object at 0x10ec4b110>
[2] pry(main)> po.__pyptr__.__ob_refcnt__
=> 2
[3] pry(main)> PyCall::PyPtr.decref(po.__pyptr__)
=> #<PyCall::PyPtr:0x3fc2eb0a7ab0>
[4] pry(main)> po.__pyptr__.__ob_refcnt__
=> nil
[5] pry(main)> po.__pyptr__.__address__
=> 0
[6] pry(main)>
