I'm using php7 with CentOS 7.2. I had to install "php70w-pecl-xdebug.x86_64". I also added the following the Dockerfile

RUN echo "xdebug.idekey = PHPSTORM" >> /etc/php.d/xdebug.ini &&
echo "xdebug.default_enable = 0" >> /etc/php.d/xdebug.ini &&
echo "xdebug.remote_enable = 1" >> /etc/php.d/xdebug.ini &&
echo "xdebug.remote_autostart = 0" >> /etc/php.d/xdebug.ini && \

• data segment - globals, literals
• stack - go routine (2k per go routine)
