_multiprocessing.Connection() allows to use any positive (or nul) number has socket handle. If you use an invalid file descriptor, poll() method may crash (especially for big positive integer). Example: >>> import _multiprocessing >>> obj = _multiprocessing.Connection(44977608) >>> obj.poll() Erreur de segmentation (core dumped) Fix: use fstat() to make sure that the handle is valid. Attached patch implements this feature. Another solution would be to reuse code from Modules/selectmodule.c.
