Recursively getting __call__ method from existing __call__ causes interpreter infinitely grow in memory and calling resulting __call__.__call__...__call__.__call__() chain results in crash. Platform: Windows 7 (x64) Version: Python 2.7 (r27:82525) win32 Suggested solution: * let the obj.__call__.__call__ point to obj.__call__ |

I can duplicate this as a segmentation fault under 2.7 on Mac OS, but not under Windows 2.6 (ActiveState). What platform are you using, and what output do you see? |

On Windows, a stack overflow often causes the program to silently exit. Try to add some print statement at the end and see if it executes. |

This seems to be another case of "C stack depth not reflected in the stack counter". |

Amaury: Good point. The Windows version is failing, too. A print statement at the end doesn't get executed. |

“Recursively getting __call__ method from existing __call__” I wonder what is the use case for this. |

I doubt there is a good usecase for it, nevertheless we should attempt to fix it, as segfaults are no good. |
