i'm trying out a groupware in php (downloaded
from http://www.horde.org/, latest cvs)...

according to that documentation it was recommend
to download the latest cvs-revision from php in
order to get everything working...

cause earlyer versions of php (including 4.0.6)
don't support all the functions used there, i 
wasn't able to check the them against the bug, too.


(p.s: please excuse my bad english... :->)


server child crashes during the call of "mdecrypt_generic",
but not allways on every call (just the 2nd or 3rd...)


example follows:

----- cut -----

<?php 
    function testit()
    {
           if (function_exists('mcrypt_module_open')) {
            $key="3224e91c21ee5dd7e9bd83c79290bbda";
            $ciphertext="3224e91c21ee5dd7e9bd83c79290bbda";
            $td = mcrypt_module_open(MCRYPT_GOST, '',
MCRYPT_MODE_ECB, '');
            $iv =
mcrypt_create_iv(mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
            @mcrypt_generic_init($td, $key, $iv);
            error_log("BEFORE");
            $decrypted_data = mdecrypt_generic($td,
$ciphertext);
            error_log("AFTER");
            mcrypt_generic_end($td);
            return $decrypted_data;
        } else {
            include_once 'Crypt/HCEMD5.php';
 
            $hcemd5 = new Crypt_HCEMD5($key);
            return $hcemd5->decodeMimeSelfRand($ciphertext);
        }
    }
  testit();
  echo("aaaa");
?>
----- cut -----


now the backtrace follows:
