Turning off the "Load symbols lazily" option worked for me.   It's  

not optimal, but at least it's letting me use the debugger now.  Thanks!

I am uncertain why this worked, and Xcode 2.1 debugging continues  

to be slow and flaky in many other regards.

Today I also ran into problems with debugging my C++ tool (which had never happened before) because GDB would hang after some time if I tried to step in or step over. The hang would not happen if I just hit continue and the tool would exit normally. I then tried to find if there was a reproducible case. I activated two breakpoints in different source files and it did hang in the same place (3 times after executing a while loop). I went to the target of my C++ tool in XCode and deactivated the zero link option. Then I rebuilt my tool and the hang did not happen again. I then cleaned up my target, activated zero link, and rebuilt it and tried to debug it so that I could reproduce the hang and file a bug. However, this time the hang did not happen even with zero link activated.

So, I have to agree that debugging with XCode GUI is sometimes flaky. Sometimes it works, sometimes it doesn't, which is not very helpful for reporting a reproducible bug. I'll keep a watchful eye if I can find a reproducible situation and file a bug on this.
