[New-bugs-announce] [issue19186] expat symbols should be namespaced in pyexpat again

[AThompson]

New submission from AThompson:

The issue with confliciting expat versions has poped up again in python 3.
http://bugs.python.org/issue1295808

It looks like the fix for this was removed when upgrading to expat 2.1 in http://hg.python.org/cpython/rev/e4dc8be9a72f      on Sat, 14 Jul 2012 14:12:35 -0700 Gregory P. Smith
--- a/Modules/expat/expat_external.h
/* Namespace external symbols to allow multiple libexpat version to
-   co-exist. */
-#include "pyexpatns.h"

Same backtrace as before.
