Description:
------------
The driver is loaded ("php -m"and/or "phpinfo()" show it with both versions), But when the code wants to connect to the DB, it fails with segmentation fault 11. The next code has no output at all. I have executed the code with the built in PHP 5.3.15 and with PHP 5.5.33 (build  according to the following page: http://php-osx.liip.ch).

Test script:
---------------
<?php

try {

  $user='??????';
  $password='xxxxxx';
  $connStr1 = "ibm:test01";
  $connStr2 = "ibm:DRIVER={IBM DB2 ODBC DRIVER};HOSTNAME=127.0.0.1;DATABASE=TEST01;";

  $option = array(
    PDO::ATTR_PERSISTENT => TRUE,
    PDO::ATTR_CASE => PDO::CASE_NATURAL,
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
  );

  $conn = new PDO($connStr1, $user, $password, $option);
  // $conn = new PDO($connStr2, $user, $password); //, $option);

  echo "Connection is established... db: test01, user: aperger" . PHP_EOL;

  $attributes = array(
    "AUTOCOMMIT", "ERRMODE", "CASE", "CLIENT_VERSION", "CONNECTION_STATUS",
    "ORACLE_NULLS", "PERSISTENT", "PREFETCH", "SERVER_INFO", "SERVER_VERSION",
    "TIMEOUT"
  );

  foreach ($attributes as $val) {
    echo "PDO::ATTR_$val: ";
    echo $conn->getAttribute(constant("PDO::ATTR_$val")) . PHP_EOL;
  }

}
catch (Exception $e) {
  ($e->getMessage());
}

?>

If that segfault is still reproducible with any of the actively
supported PHP versions[1] and the latest PDO_IBM, please provide a
stack backtrace[2].
