Bug description:  CLI binary segfaults on ldap_bind(), Apache module works fine

Description:
------------
ldap_bind(), whether anonymous or not, produces a Segfault when run from 
the command line. This is occurring on 5.2.3 (and I can reproduce it on 
5.2.1). Please note that 5.1.6 does not have this problem.

Reproduce code:
---------------
$ds = ldap_connect("ldaps://ldap.example.com");

if($ds) {
  echo "Connected\n";

  // Anonymous bind
  $br = ldap_bind($ds);

  // Use this for authenticated binds
  //$br = ldap_bind($ds, $argv[1], $argv[2]);

  echo "Bind result: $br\n";
}



Expected result:
----------------
Connected
Bind result: 1





Actual result:
--------------
Connected
Bind result: 1
Segmentation fault
