Description:
------------
I have a private key & self-signed certificate.
1) create a signature (openssl_pkcs7_sign)

2) verify the signature: function openssl_pkcs7_verify returns TRUE (Verification successful),
   but openssl_error_string() - returns an error message (error:2107C080:PKCS7 routines:PKCS7_get0_signers:signer certificate not found)

3) in the command line are no errors
   openssl smime -sign -nocerts -signer proc.crt -inkey proc.key -in in.txt -out signed.txt
   openssl smime -verify -noverify -nointern -nochain -in signed.txt -certfile proc.crt


Reproduce code:
---------------
<?
    file_put_contents("in.txt", "demo text");

    $certfname='./proc.crt'; 
    $crt      =file_get_contents($certfname);
    $priv_key =file_get_contents('./proc.key');

    if(openssl_pkcs7_sign("in.txt", "signed.txt", $crt, $priv_key, array(), PKCS7_NOCERTS))
    {
       $status=openssl_pkcs7_verify("signed.txt", PKCS7_NOVERIFY|PKCS7_NOINTERN|PKCS7_NOCHAIN, "1.tmp", array(), $certfname);
       while($msg=openssl_error_string()) echo "$msg\n"; 
       echo "status=$status\n";
    }
    else die('failed openssl_pkcs7_sign');
?>


Expected result:
----------------
status=1

Actual result:
--------------
error:2107C080:PKCS7 routines:PKCS7_get0_signers:signer certificate not found
status=1
