title: Composer Segmentation Fault when installing bundle on symfony 3
body: <p>I am working with Symfony 3 framework and I would like to add a new bundle using GIT Bash console.</p>
  
  <p>When I run the following command:</p>
  
  <pre><code>$ composer require doctrine/doctrine-migrations-bundle
  </code></pre>
  
  <p>I get the following error:</p>
  
  <p><strong>Using version ^1.1 for doctrine/doctrine-migrations-bundle
  ./composer.json has been updated
  Loading composer repositories with package information
  Updating dependencies (including require-dev)
    - Installing zendframework/zend-eventmanager (3.0.1)
  /c/ProgramData/ComposerSetup/bin/composer: line 10:  6388 Segmentation fault      php "${dir}/composer.phar" "$@"</strong></p>
  
  <p>Does anybody have any clue how can I fix this?</p>
  
  <p>Thank you,</p>
