Summary: Stepping into a generator throw does not work

Initial Comment:
Python version: 2.6
Platform: Windows XP

Stepping into a throw of an iterator with the debugger
does not work.

To reproduce:

1. Run the attached script
2. type 's' for single step once you see the debugger
prompt.

I am getting this backtrace:

  File "C:\bwm\Cruiser\play\microthreads\post.py", line
24, in <module>
    it.throw(E, E())
  File "C:\bwm\Cruiser\play\microthreads\post.py", line
7, in f1
    (yield (2,(self.f2,(exc_class,))))
  File "C:\Python25\lib\bdb.py", line 50, in trace_dispatch
    return self.dispatch_call(frame, arg)
  File "C:\Python25\lib\bdb.py", line 79, in dispatch_call
    self.user_call(frame, arg)
  File "C:\Python25\lib\pdb.py", line 134, in user_call
    self.interaction(frame, None)
  File "C:\Python25\lib\pdb.py", line 185, in interaction
    self.setup(frame, traceback)
  File "C:\Python25\lib\pdb.py", line 109, in setup
    self.stack, self.curindex = self.get_stack(f, t)
  File "C:\Python25\lib\bdb.py", line 318, in get_stack
    i = max(0, len(stack) - 1)

I got the Python version wrong above. The problem has been observed with
Python 2.5, not 2.6 (don't know about other Python versions).
