Installing D7 will cause Apache to crash

At first I thought I was imagining this but it's reproducible. I'm running Windows 7 (6.1 Build 7600) with a XAMPP set up, and basically installing Drupal will crash Apache 2.2. The fault occurs when pressing submit on MySQL credentials. The server will stop responding and eventually you'll receive a notice that Apache has crashed.

Version info:
* Windows 7 (6.1.7600, 32bit, 4GB RAM)
* Apache 2.2.11 (Win32)
* PHP 5.2.8
* MySQL 5.1.30
* PDO_MYSQL version 5.1.30
