Description:
------------
If you connect to a non-existing host via mysqli_connect() or mysql_connect() you'll get an 500 Internal Server Error on Windows 7 SP1 with IIS 7.5 and PHP 5.6.2.

With PHP 5.4.32 an error message is shown.

Test script:
---------------
$conn = mysqli_connect(
    'xxxxxxxxxxx',
    'test',
    'test'
);

Expected result:
----------------
Show an error message that cannot connect to host.

Actual result:
--------------
500 Internal Server Error

That's what i see running your snippet:

Warning: mysqli_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known.  in Command line code on line 1

Warning: mysqli_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No such host is known.  in Command line code on line 1

Could you please retry with the debug symbols? Maybe some backtrace can be seen in the event log then, or even it could produce a dump. Or use the DebugDiag, it can do it as well.

Thanks

With PHP 5.6.3 the problem is no longer reproducible (Windows 8.1).
