[New-bugs-announce] [issue26551] Regex.finditer infinite loops with certain input

[Alan Mislove]

New submission from Alan Mislove:

I found a regex and input that causes re.finditer() to appear to get into an infinite loop.  Please see the attached minimal python script that triggers the behavior.  I've verified the bug exists on 2.7.6, 3.4.0, and 3.5.1; I haven't yet be able to test whether it also exists in the latest 3.6.
