mcrypt_create_iv(mcrypt_get_iv_size (MCRYPT_DES , MCRYPT_MODE_ECB), MCRYPT_RAND) produces following error and causes apache to segfault:

Warning - String is not zero-terminated
source: zend_execute_API.c:274


Workaround:

Replace the mcrypt_create_iv call with:
      $fp = fopen("/dev/random", "r");
      $iv = fread($fp, mcrypt_get_iv_size (MCRYPT_DES , MCRYPT_MODE_ECB));
      fclose($fp);

Better: Should be fixed.
