Description:
------------
When using openssl_pkcs7_encrypt, Apache seg faults. I can perform the same smime related function with openssl alone but not in PHP.

I have tried different sized messages, different headers, different certs, etc and it always seg faults.

Reproduce code:
---------------
            $headers_array = explode("\r\n", $header);
            $infilename = tempnam("/tmp/", "smime-in-");
            $outfilename = tempnam("/tmp/", "smime-out-");
            unlink($outfilename);

            $fp2 = fopen($infilename, "w");
            fwrite($fp2, $mimeData.substr($message, strpos($message, "\r\n\r\n") + 2)."\r\n");
            fclose($fp2);
            $cert = $cert_array[0];
            $encrypted = openssl_pkcs7_encrypt($infilename, $outfilename, $cert, $headers_array, 0);


Expected result:
----------------
smime encrypted data to be written to $outfilename.

Actual result:
--------------
When ran in a browser the page stays the same and doesn't move on to the page the code is being ran on and I get "child pid 5314 exit signal Segmentation fault (11)" in the Apache error log. When ran from the command line I get a sefmentation fault and a core dumped.

Here is the backtrace. Doesn't seem to be much there.
