Description:
------------
Maybe this is a bug in MySQLnd and not MySQLi, so feel free to change the affected package. With libmysql this is working as expected.




Test script:
---------------
<?php
error_reporting(E_ALL);

$con1 = mysqli_init();

mysqli_ssl_set($con1,
    "nonexistent",
    "nonexistent",
    "nonexistent",
    null, null
);


if (!mysqli_real_connect($con1, 'localhost', 'foo', '')){
    printf("Connect Error: %s\n", mysqli_connect_error());
    exit;
}
printf("Connected.\n");

$res = mysqli_query($con1, "SHOW STATUS LIKE 'Ssl_cipher'");
printf("SSL-Connection: %d\n", (bool) end(mysqli_fetch_row($res)));
?>


Expected result:
----------------
SSL error: Unable to get certificate from 'nonexistent'

Warning: mysqli_real_connect(): (HY000/2026): SSL connection error in
C:\Users\Public\Documents\htdocs\test.php on line 21
Connect Error: SSL connection error


Actual result:
--------------
Connected.
SSL-Connection: 1
