I tried to run a Drupal 7 installation on my local environment which previously worked totally fine. I use Mac OS X. When requesting the website locally the browser shows:
Parse error: parse error in /Library/WebServer/Documents/.../xxx.module on line 7
Line 7 is
$variables['path'] = $base_url . "/sites/default/files/" . explode('public://',$file->uri)[1]
OR it returns an error with the code:
ERR_EMPTY_RESPONSE
The apache error file shows:
child pid 2114 exit signal Segmentation fault (11)
php -v returns

The code seems not to be wrong. It's exactly the same running on another machine.
