Please file a bug and include the Xcode-gdb log (in Xcode 3.0 you can
turn the log generation on and off in the Debugging pane of the Xcode
Preferences.)

I've got a launchd daemon that I'm trying to debug. I have
WaitForDebugger set to YES in my launchd plist file. When the

10/29/07 2:58:48 PM com.apple.launchd[108]
(com.foo.daemontest[3887]) Spawned and waiting for the debugger to
attach before continuing...
Then if try to attach to this process with Xcode, I get the
following errors:
Attaching to program: `/Users/dustin/XcodeBuild/Debug/daemontest',
process 3887.
Xcode: Introspection dylib not loaded because thread 1 has function:

Any attempts to step or continue the process result in this output:
Program received signal: “EXC_BAD_ACCESS”.

I have been able to successfully attach using gdb via Terminal. I
have not tried this with Xcode 2.x.
Is this a supported operation with Xcode? Are there any workarounds?
Thanks,
Dustin
