Closing this, I found the source of the problem - missed changing the
path when I upgraded. A week of testing everything I can think of to
figure out what was going wrong and miss that - go figure.

Works fine for me on Linux. Do you have other extensions loaded?

Description:
------------
Encryption appears to work, as plain text becomes ciphertext, but
decryption using either the mcrypt_decrypt or mdecrypt_generic
functions returns the ciphertext unchanged as the result of the
function call.


Reproduce code:
---------------
$key = "ae2b1fca515949e5d54fb22b";
$td = mcrypt_module_open ('tripledes', '', 'cbc', '');
$iv_size = mcrypt_enc_get_iv_size ($td);
$iv = mcrypt_create_iv ($iv_size, MCRYPT_RAND);

if (mcrypt_generic_init ($td, $key, $iv) != -1) {
    /* Encrypt it */
    $c_t = mcrypt_generic ($td, "testing");
    mcrypt_generic_deinit ($td);
    echo "ciphertext: ". $c_t;

    /* Decrypt it */
    mcrypt_generic_init ($td, $key, $iv);
    $p_t = mdecrypt_generic ($td, $c_t);
    echo " plaintext: ". $p_t;

    mcrypt_generic_deinit ($td);
    mcrypt_module_close ($td);
}



Expected result:
----------------
This should produce the following:

ciphertext: _sometext_ plaintext: testing

Where _sometext_ is the ciphertext created based on the random input
vector. 
E.g.
ۏÖæ‚È«


Actual result:
--------------
ciphertext: ۏÖæ‚È« plaintext: ۏÖæ‚È«
