If you put together a small project which shows the problems you are
having then it would be great if you could file a bug and put that in
it.
Otherwise, we are all just speculating...
Another couple of things you can do:
1) This is the standard Xcode Debugger debugging procedure:
1) Quit Xcode.
2) In Terminal, say:
$ defaults write com.apple.Xcode PBXGDBDebuggerLogToFile YES
$ defaults write com.apple.Xcode PBXGDBDebuggerLogFileName /tmp/
IncludeInBug.log
3) Restart Xcode, and exercise it to make it show the bad behavior.
4) Attach /tmp/IncludeInBug.log to the Radar.
Another interesting thing would be to see whether gdb & Xcode agree
about your sources. After you have set your breakpoints, and run
your program, interrupt it, open the Debugger console, and do:
(gdb) info break
Take some of the file:line specs that you get from gdb for the
breakpoints, and do:
(gdb) list file:line
Do these match the file & line listings you get from Xcode? For
instance, if you have \r\n or some other line ending that confuses
Xcode, usually these don't confuse gdb. You could then back up in
the gdb listings till you find the place where Xcode & gdb get back
on track, and see if there is something funny in the file there.

I see this on a regular basis.
I see it periodically, but I found it's caused by uncompiled
changes in the code. I've also seen it happen when I've had a
second version of the code open that has break-points in it
(debugger breaks on all the combined break-points).
This problem caused me no end of frustration until somebody
pointed out that it might be caused by \r\n line endings. I
cleaned up all of my files, and the problem disappeared.
Neither case applies to me. All my files are unique, and none
contains \r (I checked with find, od, and grep).
