I just upgraded to PHP 5.4.2 and the test script still crashes PHP. I have run
the script on two different Windows servers. I am running IIS with fastCGI.

Just checked again: This was already fixed in
https://github.com/php/php-src/commit/da6465a268d9ece2ffd38447890b206dd94b3250,
that's why it was running fine for me.
So this should be fixed in PHP 5.4.1 :)

Yes, it crashes at the command line too. The windows event logs record the
crash.

This script runs fine on CLI for me. Could you see whether running on CLI works
for you?

Description:
------------
If a class overrides a method but with a different signature and that method is
called in the constructor and if error_reporting is set to display strict
errors and if the classes are defined in reverse order, PHP will crash. In my
test script, if class one is defined before class two, PHP won't crash. I
realize that overridden methods need to have identical signatures, but I would
expect a warning and not a crash.
Test script:
---------------
error_reporting(-1);
class two extends one{
public function __construct(){
$this->error(7);
}
private function error($n){
echo 'two';
}
}
class one{
private function error(){
echo 'one';
}
}
new two;
Expected result:
----------------
two
Actual result:
--------------
FastCGI Error
The FastCGI Handler was unable to process the request.
Error Details:
The FastCGI process exited unexpectedly
Error Number: -2147467259 (0x80004005).
Error Description: Unspecified error
HTTP Error 500 - Server Error.
Internet Information Services (IIS)
