I am getting "Invalid parameter detected in CRT function '_get_osfhandle'" when running the below code. 

I have compiled a source code snapshot version of PHP 5.3.2-dev on Windows. I used VC9 Express and SDK 6.1 . OS is XP Prof. I've run PHP from within the build tree in the hope it will pick the binaries (dlls, resource files, whatever there is) I have compiled myself. 

However, I have also seen this warning with yesterdays VC9 non TS binaries from the on another box. A couple of ext/mysqli tests fail because of the warning. The affected mysqli API calls is mysqli_poll(). It makes use of [php_]select() just like the below code.

Reproduce code:
$stream = stream_socket_client("tcp://", $errno, $error, $whatever, STREAM_CLIENT_ASYNC_CONNECT | STREAM_CLIENT_CONNECT);
$read = $write = $except = array($stream);
var_dump(stream_select($read, $write, $except, 1));

Expected result:
No warning. 

Actual result:
resource(5) of type (stream)

Warning: Invalid parameter detected in CRT function '_get_osfhandle' (f:\dd\vctools\crt_bld\self_x86\crt\src\osfinfo.c:314) in E:\php-sdk\php53dev\vc9\x86\php5.

I am getting the same bug with the PHP 5.3.3RC1 VC9 x86 Thread Safe build. The 
server is a Windows 2008 R2 x64 machine. The code that is producing the error 
for me is:

error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', 1);

$con = fsockopen('', 80);
$read = array($con);
$write = NULL;
$except = NULL;
stream_select($read, $write, $except, 1, 0);

The error is:
Warning: Invalid CRT parameters detected in C:\tmp\stream_select.php on line 10

I can probably provide access to the machine if need be.

Same on with VC9 binaries from 5.3.3-RELEASE using the non-threadsafe version. So basically anything with VC9.

The warning I get (both Windows XP and Windows Vista) is:

  "Invalid CRT parameters detected"

I'm using the second example (w/ fsockopen(""[...])).

I got the same problem with PHP5.3.3 on Windows7 (6.1.7600) and maybe with 5.3.2 too. Problem comes from stream_select and produces a warning: invalid CRT.

I got the same problem with PHP5.3.4 on Windows7 (6.1.7600).

Same issue on Windows 7 64bit + PHP 5.4 (Zend Server Community Edition).

I cannot reproduce that with current PHP-7.3. Presumably, the
issue has been fixed in the meantime, or can somebody else
reproduce it with any of the actively supported PHP versions[1]?
