Segmentation fault between 5.5 and 5.6 with remote address in stream socket

Hello internal, I have just opened a new bug, https://bugs.php.net/72439 (source of the story https://github.com/hoaproject/Websocket/issues/66). It seems to be a regression between 5.5 and 5.6. I quickly suspect https://github.com/php/php-src/commit/4a2e40bb861bc3cf5fb6863e57486ed60316e97c to be the source of this regression but I need to dig into it a little bit more. Any one has an idea? Cheers!
