Description:
------------
Calling functions "getMyUid()" followed by "get_current_user()", or vice versa, crashes the following environment...

Server software as reported by PHP:
Apache/2.0.52 (Win32) mod_perl/1.99_16 Perl/v5.8.4 PHP/5.0.2 mod_ssl/2.0.52 OpenSSL/0.9.7d mod_python/3.1.3 Python/2.3.3

The OS used is Win2k SP4 including all available patches.

NOTE: The crash also occurs when "get_current_user()" is used in combination with "getMyGid()", "getMyPid()" and probably other related functions.

Reproduce code:
---------------
<?php

	echo("Crash test<br />\n");
	$sUser = get_current_user();
	$nUID = getmyuid();
	echo("Result, get_current_user(): ". $sUser ." / ". $nUID);

?>

Expected result:
----------------
Crash test
Result, get_current_user(): SYSTEM / 0

Sorry, but I made a mistake when I was analyzing this bug.

The crash will always happen as soon as the function "get_current_user()" is called. It doesn't have to do anything with the other functions I mentioned above.

The problem I've had seemed to be Apache, which takes forever to restart on my machine. Therefore I got a little bit confused when commenting out certain lines of code.

You may close this report if you wish to. I think there is another report regarding the crash with "get_current_user()" - maybe you should reopen it, if closed, since the bug is still there.

Sorry again...
