[issue9955] multiprocessing.Pipe segmentation fault when recv of unpicklable object

2011-06-26 Thread Kristian Vlaardingerbroek 

Kristian Vlaardingerbroek kristian.vlaardingerbr...@gmail.com added the 
comment:

On Python 2.7.2 this can not be reproduced. Instead of the segmentation fault 
an AssertionError is raised:

AssertionError: invalid Element proxy at 39359432

In Python 3.2 the p1.send(n) step in the example raises a PicklingError when 
trying to pass an unpickable object.

Recommend closing this ticket.

Can't reproduce on Python 2.7, but can indeed reproduce on 2.6.  Issue fixed?
