XCode Error - "Cannot access memory at address 0x4"

I've gone back through the archives for a bit, but haven't seen anything like this. Google is a disappointment as well.

I'm on Leopard with XCode 3, and when I try and debug an application, GDB chokes on it. It doesn't matter what application. Even if I just try and debug the default Cocoa Application template without a line of my own code in it, it borks.

This GDB was configured as "i386-apple-darwin".tty /dev/ttys002

Leopard on a first gen Intel MBP. Tiger and XCode 2 were installed on it at one point, and I did do an upgrade install.

I'm n00b with XCode development (I programmed a game once on Tiger, but haven't touched it in too long to remember much), so hopefully this isn't a pebkac. Has anyone seen anything like this before?

EDIT: Looks like this is a pebkac. I didn't use the uninstall script to uninstall XCode 2, so some of its binaries are sitting in /usr/bin, and I installed XCode 3, which doesn't have that cute little uninstall script.

So now, I have to figure out how to uninstall X2 without the X2 uninstall script.

I am having the same problem. I cannot for the life of me figure out what is going on. I had Xcode 2.5 installed too, but I thought having both 2.5 and 3.1 installed at the same time was supported. I removed both and reinstalled Xcode 3.1, but I still have the problem.
Did you uninstall 2.5 properly? Every file related to it has to go. Use the script, or if the script isn't there anymore, get it off your old OS CD or a friend's.
