No: CarbonCore is there, present, working, and you are running its Debug binary. Then you're making a file system call (something that calls down to FSPathMakeRef). And it's getting an fnfErr. And the debug version of CarbonCore asserts, and your app terminates.

So: your app is trying to create an FSRef with a path to a nonexstent file, and the debug CarbonCore is asserting because of it.

Thanks, Chris. I get it. Very strange, though, that this occurs with a "New Cocoa Application", right out of the box (see step 4. above). "I" am not making that file system call; apparently Cocoa is. Unfortunately the log output does not tell me the path that failed nor the calling function, so I have no idea where to look.

Moving beyond this, I found that if I run "Debug" instead of "Run", the app does not terminate. I'm not sure why this is. Same thing if I Debug my real app.

I wonder about the other noise I'm getting too. For example, after gdb loads I there are maybe 1000 warnings logged similar to these three:

This GDB was configured as "i386-apple-darwin".tty /dev/ttys000 warning: Could not find object file "/var/tmp/Libsystem/ Libsystem-111~826/i386/objroot/objects-debug/System_vers.o" - no debug information available for "/var/tmp/Libsystem/Libsystem-111~826/i386/ symroot/System.build/derived_src/System_vers.c".

warning: Could not find object file "/BinaryCache/Libsystem/ Libsystem-111~826/Root/usr/local/lib/system/libc_debug.a(zone.o)" - no debug information available for "/SourceCache/Libc/Libc-498/gen/zone.c".

   ... hundreds more like this

It looks like these are telling me that gdb cannot debug or symbolize system libraries. OK, that makes sense. But is it normal to have this logged hundreds of times, apparently one for each binary?

After all this finally got done logging, I was able to run my app, create a document, do an import and some editing, and save it. But during this time I had to click "Continue" in the debugger hundreds of times. Besides the fact that it really doesn't like my usage of FSDetermineIfRefIsEnclosedByFolder() for some reason, there were hundreds of other inexplicable breaks, like these for example:

Xcode could not locate source file: __pthread_kill.s (line: 5) Xcode could not locate source file: __pthread_kill.s (line: 5) (gdb) continue 2009-09-01 05:16:00.173 BookMacster[89205:b0f] DebugAssert: HIToolbox: data != NULL exception_GetWindowClass_InvalidWindowPtr [./Windows/ Source/WindowClass.cp:1075] Xcode could not locate source file: __pthread_kill.s (line: 5) Xcode could not locate source file: __pthread_kill.s (line: 5) (gdb) continue

I pasted in some more at the end (*).

I am happy that I only found only a couple potential issues, and no assertions from Core Data.

Is my experience with the debug library typical? Is there any way to reduce the noise level?
