If the breakpoints window shows a '-' in the enable/disable checkbox, while debugging, then the breakpoint is 'pending'. This means either A: compiler didn't generate symbols for that file/function so the debugger couldn't find a location for the breakpoint, B the debugger has not yet loaded the full debugging symbols or C the shared library/bundle that contains the code in question has not been loaded. Does the debugger stop at symbolic breakpoints? Can you debug any of the ObjC examples in /Developer/Examples/AppKit?
A. Make sure you are building with a build configuration that is generating debugging symbols. Check the target build settings and the detailed build log for ether '-g', '-gused' or '-gfull' is set when compiling the sources you are breaking on.
B. Try going to the shared libraries window via the menu Debug->Tools->Shared LIbraries... and changing the Default Level for User Libraries to 'All'. Start debugging.
C. If the addresss in the Shared Libraries window is non-zero then the module is loaded.
If non of that resolves things then you need to file a Radar with the Xcode-gdb log.
Do the following in terminal then run Xcode, reproduce the problem and attach the log to your Radar:
defaults write com.apple.Xcode PBXGDBDebuggerLogFileName /tmp/XCGDBLog defaults write com.apple.Xcode PBXGDBDebuggerLogToFile YES

I've just installed Tiger & XCode and it isn't stopping at *any* breakpoints in the ObjC program (which I did not write, source download) I'm trying. Looking at the GDB window also I see is the "run" being issued. The breakpoints window shows the breakpoints. I thought I'd missed something really obvious, but maybe I'm not quite that thick given Bob's request (unless we're a pair ;-)). Anybody enlighten me as to how to get breakpoints to fire?
TIA, Nigel
