New Comment:
Your expected result is wrong, you can not isset on an addition to an
array.
Besides that, i could reproduce this on Linux too.

Description:
------------
When using a simple isset() script crashes PHP5.
Reproduce code:
---------------
<?
$array = array('foo' => 'bar');
if (isset($array[])) echo "Something";
?>
Expected result:
----------------
The expected result is to echo "Something"
Actual result:
--------------
Actual result is a "Apache.exe has encountered a problem and needs to
close. We are sorry for the inconvenience." error in PHP5TS.DLL,
running as a Module on Apache 1.3.31.
Debug tool with Microsoft Visual Studio returns this:
"Unhandled exception in Apache.exe (PHP5TS.DLL): 0xC0000005: Access
Violation"
