Python2.7.11+ as distributed by Ubuntu 16.04LTS and Debian testing crashes with a segmentation fault when running a simple Zope2 instance.'s Python2.7.11 does not exhibit the same crash.

It is possible that one of the patches in debian/patches or another factor of the Debianization introduces a regression or a new issue.

The issue has been registered with Ubuntu here:

Matthias Klose, Debian maintainer for the package, has asked me to
report this problem upstream, because otherwise we will invariably run
into this regression in 2.7.12.

I have attached the script I use to produce the segmentation fault. I involves installing Zope2 from the internet, but other that that, it only requires a standard Python2.7 installation (with zlib support).

I have also succeeded in calling and producing this error in gdb, but I don't know how to move on from there.

Any hints on how I can locate the problem are very welcome!

2.7.11+ translates to 20160330 from the 2.7 branch.

FWIW, I am also unable to reproduce the crash on OS X with a current top-of-2.7 debug build.  Since it doesn't seem to be able to be reproduced with stock Python 2.7's, perhaps it is time to close the issue here?

I'm unable to reproduce this with the 2.7 branch 20160603.

(checked with the recent packages in Debian unstable and Ubuntu yakkety)
