[issue32235] [2.7 regression] test_xml_etree test_xml_etree_c failures with 2.7 and 3.6 branches 20171205

[Matthias Klose]

Matthias Klose  added the comment:

ok, I can confirm that the failures go away with an updated version.  Then 
trying to find documentation about required external dependencies...  None.  
While we have pointers to optimize the build, we don't have anything about 
requirements in the toplevel README.md.

See bpo-31170 for expat 2.2.3 bug (and maybe also bpo-30947).

Serhiy Storchaka  added the comment:

This means that you need to update the expat library. Expat version 2.2.3 
contains a bug, it affects not only Python, but all depending applications.
