Executing the code you posted results in a crash inside the PHP module. I assume you’re running PHP as module inside apache on windows, if the module crashes, apache crashes as well.
Ensure that you’re using the right PHP modules here. Are you sure you need the Thread-Safe variant of PHP for apache? Those are reported to not run stable under windows IIRC.
So this might not be related to the wordpress version but to the server configuration.
Hope this answer helps a bit tackling things down.
