I can't make a guess at what's going on without more data. But if
you can file a Radar on this with the following, I'll be glad to take
a look:
There are two pieces of information that will help right off.
The first is the transcript of the communication between Xcode &
gdb. To get that, do:
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 do whatever you need to to make it fail.
4) Attach /tmp/IncludeInBug.log to the Radar.
The second is to sample gdb when it is hung. You can start up /
Developer/Applications/Performance Tools/Sample.app, and the attach
to the gdb process, and click the "start" button to sample it for a
little bit. Then save the sample and attach that to the bug.
Thanks,
Jim

Hi folks,
I'm relatively new to Xcode. I've recently ported our CodeWarrior
project to Xcode 2.1, and it's compiling and running fine, but I'm
having trouble using the debugger.
When I set a breakpoint and debug the program, the application
launches fine and drops into the debugger when I hit the
breakpoint. Xcode displays the stack, a few local variables, and
shows me the source code at the breakpoint. However, the Activity
Monitor immediately shows gdb-powerpc-appl taking up all the
available CPU time, and the debugger in Xcode is unresponsive. I
can hit buttons to single-step, display variables, etc. but nothing
actually happens. I can click the Terminate button to kill the
application, and Xcode appears to be fine after that, but I can't
actually use the debugger.
Any ideas as to what's going wrong, or even how I might go about
tracking down the cause of the problem?
Thanks,
