Bug description:Memory leaks when openssl_encrypt called

Description:
------------
Related bug #54060, http://bugs.php.net/bug.php?id=54060

Memory leaks when I call openssl_decrypt. Test script shows that. I've
watch at ext/openssl/openssl.c and according to
http://www.openssl.org/docs/crypto/EVP_EncryptInit.html (see example at the
bottom) you should free cipher_ctx.



<?php



$data = "jfdslkjvflsdkjvlkfjvlkjfvlkdm,4w 043920r 9234r 32904r 09243
r7-89437 r892374 r894372 r894 7289r7 f  frwerfh i iurf iuryw uyrfouiwy ruy
972439 8478942 yrhfjkdhls";

$pass = "r23498rui324hjbnkj";



$maxi = 200000;

$t = microtime(1);

for ($i=0;$i<$maxi; $i++){

        $cr = openssl_encrypt($data.$i, 'des3', $pass, false, '1qazxsw2');

        $dcr = openssl_decrypt($cr, 'des3', $pass, false, '1qazxsw2');

        if ($dcr != $data.$i){

                print "at step $i decryption failed\n";

        }

}

$t = microtime(1)-$t;

print "mode: openssl_encrypt ($maxi) tests takes ".$t."secs
".($maxi/$t)."#/sec \n";

?>



fixes by add this code at line 4818 at the end of openssl_decrypt:

        EVP_CIPHER_CTX_cleanup(&cipher_ctx);
