Maxim hadn't posted the test case when I replied.  Even now I'm not sure what
the chain of events are.  If the second instance is when f11 is called by f1,
then I agree it should be out of scope, and I think it always has been.  If it
refers to the second time f11 is called from main (and the transcript seems to
suggest this, although I've not looked too carefully) then GDB still considers
this to be in scope.
