Right, these tests all pass on Mac OS X with 
--no-longjmp-all-nonlocal-labels.

With that option, I can now build and debug a typical Mac OS X GUI app 
(from the GPC Xcode Kit) with the gcc-4 based compiler and -gdwarf-2. 
My first impression is that debugging (with Xcode as front-end) has 
quite improved as compared to -gstabs (apart from the line-number 
problem). I will try to patch the installed system gdb with your gdb 
dwarf patches and then report the result.

Thanks.

We will see if it gets fixed -- I am glad it's reproducable with Linux 
and AMD also (...).
