Description:
------------
1) Installed via pecl -v install rar
2) Added extension=rar.so to php.ini at line 597
3) Get "Segmentation fault (core dumped)" at the end of of ALL PHP files, even if they don't use the rar package

Reproduce code:
---------------
$rar_file = rar_open('test.rar') or die("Can't open Rar archive");

$entries = rar_list($rar_file);

foreach ($entries as $entry)
{
  echo 'Filename: ' . $entry->getName() . "\n";
  echo 'Packed size: ' . $entry->getPackedSize() . "\n";
  echo 'Unpacked size: ' . $entry->getUnpackedSize() . "\n";
}

rar_close($rar_file);

Actual result:
--------------
$ php rar.php
Filename: legs.jpg
Packed size: 290808
Unpacked size: 290808
Filename: 10.jpg
Packed size: 186886
Unpacked size: 186886
