Not sure how to attach files; it wouldn't let me submit them as patches. I've uploaded
them to pastebin:

- PHP 5.6 strace: http://pastebin.com/SNuJGAZW
- PHp 7.0.4 strace: http://pastebin.com/akrFjzpT

Having trouble reproducing. Can you attach strace output for 5.6 and 7? Invoke like:

    $ strace -ttt -T -f -s1024 -o strace.log php test.php

Thanks.
