After step one of the installation, when I enter "Weblog Title" and "Your Email" and click "Continue to Second Step", Apache crashes. Also, after clicking "Continue to Second Step", any other WP page I try to access also crashes Apache (including "install.php").
If I drop the WP Database and create it again, it allows me to get to step one of the install process, but then the error happens all over again.
Here is my system configuration:
WP 1.5
PHP 5.0.3
MySQL 4.0.22
Apache 2.0.53
NOTE: I was successful installing WP on this same system running PHP 4.3.10.
I don't get any error messages printed out to the page.
