[New-bugs-announce] [issue17360] Regular expressions on mmap'd files can overflow

[Jeremy Archer]

New submission from Jeremy Archer:

I've recently been having problems with the Python regular expressions module when mmap'ing large (> 2^32 bits) on Linux.

Steps to reproduce:

https://gist.github.com/fatlotus/5094575

I've been able to replicate it on Ubuntu Linux (uname -r = 3.5.0-23-generic). Naturally, this is on a 64-bit platform with Python 2.7.3 installed from APT.
