[php-maint] Bug#805591: php5: Segmentation fault on new DateTimeZone('leap-seconds.list')

[Jonathan Champ]

Package: php5-common
Version: 5.6.15+dfsg-1
Severity: normal

Dear Maintainer,

I have a script that loops through all of the DateTimeZone identifiers and
creates a DateTimeZone instance of each one for use later in the script.

The Debian package returns an extra timezone identifier "leap-seconds.list"
that causes a segfault when you try to instanciate the object.

Test script:

  <?php
  foreach (DateTimeZone::listIdentifiers(DateTimeZone::ALL_WITH_BC) as $tz)
{
      echo $tz . PHP_EOL;
      $dtz = new DateTimeZone($tz);
  }
  echo 'Success' . PHP_EOL;

Backtrace:
