lxml segfaults while making call to extension function

[Samuel Abels]

We recently upgraded from Ubuntu 10.04 (not sure which version of lxml this included, but it was <2.9.0) to 14.04 (yes, we are late).

With the new version of lxml we are getting segfaults for code that worked fine before. I have attached a minimal test case.

Python : sys.version_info(major=2, minor=7, micro=6, releaselevel='final', serial=0)
lxml.etree : (3, 3, 3, 0)
libxml used : (2, 9, 1)
libxml compiled : (2, 9, 1)
libxslt used : (1, 1, 28)
libxslt compiled : (1, 1, 28)

The test case also needs the attached additional file.

(The test case is throwing the same error with Python 3.)

I noticed that lxml 3.5.0 from Xenial (Ubuntu 16.04) installs without breaking anything on Ubuntu 14.04; the test case runs fine with this version.

So I it was already fixed. Sorry for the noise.
