gdb debugger in xcode doesn't work

I'm trying to use direct commands to gdb through xcode's console win开发者_如何学JAVAdow when the program is paused. But the (gdb) prompt just accepts the carriage returns, and does nothing. Has anyone encountered this? I'm on the latest version of Mac OS X (10.6.2) with the XCode 3.2 beta.

If using a beta best to contact the beta mailing lists as this is the sort of issue the developers want to know.

If using a beta the first thing I would check is does this work using the previous production version

Also note that you might be under a NDA and so can only discuss with the developers.

This is a bug in the software, or an incompatibility with some setting in my system. Formatting my laptop and reinstalling the software fixed the problem.
