Summary: Lineno calculation sometimes broken

Initial Comment:
I'm running the win32 version of Python 2.3a2.  I ran into 
this when I got a traceback pointing to a wrong 
linenumber.  It also messes up debugging in 
Pythonwin.  Anyway, you can see from the disassembly 
below that something goes seriously amiss when the 
code reaches the FOR_ITER:


>>> import httplib
>>> import dis
>>> dis.dis(httplib.HTTPConnection.connect)
524           0 LOAD_CONST

              3 STORE_FAST

525           6 SETUP_LOOP
              9 LOAD_GLOBAL
             12 LOAD_ATTR
             15 LOAD_FAST
             18 LOAD_ATTR
             21 LOAD_FAST
             24 LOAD_ATTR
             27 LOAD_CONST

526          30 LOAD_GLOBAL
             33 LOAD_ATTR
             36 CALL_FUNCTION
             39 GET_ITER

781     >>   40 FOR_ITER
