Xavier de Gaye added the comment: The problem may still be reproduced by running the attached pdb_refleak.py script. Enter three times 'c' (short for the pdb 'continue' command) and the following line is printed:
pdb 3 -> pdb 2 -> pdb 1 This shows that the third pdb instance 'pdb 3', owns indirectly a reference to the second and first pdb instances. As the _signal extension module owns a reference to 'pdb 3' through its sigint_handler() method, then it also owns indirectly a reference to 'pdb 1'. ---------- Added file: http://bugs.python.org/file44925/pdb_refleak.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20766> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
