I've integrated the code for experimentation, all in NSException.m

You need to build that file with the STACKTRACE preprocessor constant  
defined .. and if you do so it adds the stacktrace as an item in the  
userInfo dictionary of the exception when it is first raised.

I've only done very basic testing with it ... the current version  
didn't seem to report symbols from the base library, though it did  
locate.load the library file information.  I wonder if it needs to  
adjust the addresses in the bfd file with some relocation information  
in order to match them to stack frame addresses?
The other problem I found when running the testsuite is that it  
crashes (in NSFrameAddress())  if the exception is raised while  
forwarding an invocation.
