http://buildbot.python.org/all/builders/x86%20Gentoo%20Non-Debug%20with%20X%202.7/builds/100/steps/test/logs/stdio
There are a lot of failures, all look as:
======================================================================
ERROR: test_simple_newobj (test.test_cpickle.FileIOCPicklerFastTests)
----------------------------------------------------------------------
It looks as the _reduce_ex() function is missed in the copy_reg module. Have no ideas how it is possible.

I also have no idea how that happened, but seems to have been a fluke. Build 101 is fine, and nothing has changed on that box.

This also happened on my Windows buildbot: http://buildbot.python.org/all/builders/AMD64%20Windows8.1%20Non-Debug%202.7/builds/195
That build is running again as build 196.
zware commentedon Nov 11, 2015
Build 196 on the Windows bot is fine. Could be a bizarre test ordering issue? Nothing else should have changed between builds 195 and 196 on the Windows bot.

Could you reproduce the failure by running tests with the same seed on these machines?

I'm duping this one to bpo-25698 because while it came later, it has a lot more information. They are clearly the same bug.
