no idea what you try to tell me with "Don't seem to have an option for bytecode-caching" - nobody but you knows how your sevrer is configured and if it is using "opcache" or "wincache" or whatever is available for the redmond-gameloader - consult your phpinfo() output

Already tried playing with the JIT value.
Don't seem to have an option for bytecode-caching.

sounds like a bug in http://php.net/manual/en/ini.core.php#ini.auto-globals-jit on windows and maybe related to bytecode cache - dunno if windows these days also is using opcache, but you can try "auto_globals_jit = 0" and 0/1 in combination with and without bytecode-caching

Not just $_COOKIE either
Severity: Notice --> Undefined variable: _GET D:\www\httpdocs\cms\system\core\Input.php 609

Description:
------------
Periodically PHP will periodically fail to populate the $_COOKIE Super global.
The logs will report that _COOKIE is undefined if you check it (depending on the reporting level) and if it's set first it will behave like a non superglobal with normal variable scope.
A restart of the Apache/PHP server corrects the issue however it hits sporadically and refused to allow us to sign in. $_SERVER reports cookie data is available.
Test script:
---------------
<?php
echo("Dumping Server!\n"); print_r($_SERVER);
echo("\n\nDumping Cookie!\n"); print_r($_COOKIE);
// Set Value
echo("\n\nSetting Cookie!\n"); $_COOKIE['TEST'] = "TEST";
print_r($_COOKIE);
// Echo
echo("\n\nTest 1!\n"); test();
echo("\n\nTest 2!\n"); test2();
// Test Function 1 (No Global)
function test() {
if ( empty($_COOKIE) )
echo("Can't find cookie superglobal!\n");
}
else {
echo("Dumping Cookie!\n");
print_r($_COOKIE);
}
}
// Test Function 2 (No Global)
function test2() {
global $_COOKIE;
if ( empty($_COOKIE) ) {
echo("Can't find cookie superglobal!");
}
else {
echo("Dumping Cookie!\n");
print_r($_COOKIE);
}
}
?>
Expected result:
----------------
Dumping Server!
