[New-bugs-announce] [issue1456] unexpected iterator behavior with removal

Joseph Armbruster report at bugs.python.org
Sun Nov 18 05:32:14 CET 2007

New submission from Joseph Armbruster:

Trunk Revision: 58651

Example of potential issue:

>>> a = [1,2,3,4,5]
>>> for x in a:
...   a.remove(x)
>>> a
[2, 4]

If this is the expected behavior of iteration in this case, my
apologies.  If this is not, I believe the issue lies in that
listiter_next does not act correctly after a listremove has occurred.

My knowledge of Python development is practically 0, so please take the
patch with a grain of salt.
