There are 2 issues. First, 2.7.2 has perhaps a couple hundred bug fixes 
since 2.7.0/2.6.6 were released. So it is possible that this particular 
problem was fixed, or at least changed. Second (leaving security issues 
aside), a Py2 bug fix will only be applied to the post-2.7.2 tip and 
only after the bug has been demonstrated to exist in the post-2.7.2 tip.

About the request for minimal code exhibiting the problem: each bug 
exposes a hole in the test suite. We try to add a new test case with 
each bug fix so fixed bugs stay fixed. So code examples not only show 
that the bug is in the latest version, but also serve as the basis for 
new tests.
