This error is printed when there is a library in dyld's list of
libraries, but we can't stat the file that is pointed to. In this
case the name of the library is "", which seems a little odd...
Try setting DYLD_PRINT_LIBRARIES to 1 in you app before you run it
(you can do this in the executable editor if you are running from
Xcode.) Then dyld will print all the libraries it is loading as it
loads them. The one before gdb gets this error should be the one
causing the problem. It would be interesting to know what it is...

I seem to be unable to debug a specific application anymore. I don't
know what or where specifically the bug is because the debugger keeps
getting an internal error in the process.
I have cleaned and rebuild the application several times, trying the
different symbol formats (STABS, dwarf) but the debug just craps out
on me with no clue as to where or what the issue is.
Any clue as to how I can find out what is happening here?
Thanks.
Here's the snippet from the console.
