Not adding user to user table during install

I’m having an interesting, but frustrating problem. When I run a WordPress install from on my local machine, the install runs fine but then hangs up right at the end. If you look at the fresh install on the localhost everything looks fine. However, when you try to login using the credentials you established during setup, you cannot login. Furthermore, if you go look at the database in phpMyAdmin, you can see that WordPress has properly added table to the database, but has not written anything to the tables (including the users table).

I have gone over all the usual tips (checking wp-config for proper settings, checking user permissions, etc), but still getting the same problem over and over. I’ve had two other experienced WordPress Developers look at everything, but they too are stumped at what is going on. I’ve done dozens, if not hundreds of local wordpress installs and am an experienced developer, so I don’t believe I am making any mistakes there.

This started happening when I switched from AAMPS to MAMP for my hosting emulator. But when I switched back to AAMPS to try to fix the problem, AAMPS would not work at all either. I also tried various fixes for MySQL (uninstall, reinstall, etc.) but still the same thing. No errors are being logged.

I was wondering if anybody else has experienced something similar and if they were able to fix it.
