That's a difference.  Dare I suggest fixing GDB?

I see this as a deficiency in the debugger, and I don't think it's
worth *in this case* obfuscating the code in GCC.  I can imagine cases
where the tradeoffs would be balanced differently, but here I think
the status quo is good.  Improvements would include, as I mentioned:

  o Fixing GDB.
  o Adding .gdbinit improvements.
  o Adding functions to use in the debugger.
