Thanks for keeping an eye on this. I was working on dependency upgrades past two weeks, see some
prepared http://windows.php.net/downloads/php-sdk/deps/
for both 5 and 7 branches. But otherwise the work on their integration and as well on the other TS
issue was stalled a bit due to holidays. Expect more activity on the new deps integration next week,
so you can grab them from http://windows.php.net/downloads/snaps/ .

Thanks.

Description:
------------
libxml2 2.9.2 has a bug, which causes deadlocks in the ZTS version.

libxml2 2.9.3 was released, which has a proper fix.
See: http://www.xmlsoft.org/news.html
See: https://bugzilla.gnome.org/show_bug.cgi?id=737851
See: https://git.gnome.org/browse/libxml2/commit/?id=620a70615e68b30db1a80a993180a41dc24f12b9

Stacktrace of my affected PHP installation:
https://www.dropbox.com/s/4xzfz3mncqzw8bk/xmllock.png?dl=0

Any chance to get new versions of PHP 5.5/5.6/7.0 with the new libxml2 version?

I know PHP 5.5 is only in "security fixes only". Is this critical enough to qualify
aswell?

Test script:
---------------
not required

Expected result:
----------------
No deadlocks

Actual result:
--------------
Deadlock
