PHP7.1/Xdebug crashed on MacOs
<p>I recently reinstalled MacBook. Before installing MacOs everything worked fine. After installing MacOs, I installed php7.1 and xdebug on macos (sierra 10.12 (16A323)) with brew.</p>

<pre><code>brew install homebrew/php/php71
brew install homebrew/php/php71-xdebug
</code></pre>

<p>After installation, I configured nginx, php.ini (php-fpm) and PhpStorm. See: <a href="https://www.jetbrains.com/help/phpstorm/2016.2/configuring-xdebug.html" rel="nofollow">https://www.jetbrains.com/help/phpstorm/2016.2/configuring-xdebug.html</a></p>
