I've found a rather simple bug in the default CPython implementation on Mac OS X 10.9.5

1) Create a new .py file containing:

def a():
    print q

x=5


2) Open Python and run using execfile() then a(). Receive error as expected:

  File "test.py", line 2, in a
    print q
NameError: global name 'q' is not defined

3) Edit file so that "print q" is not "print x", and save.

4) Run a() (Do not use execfile!)

5) Error:

  File "test.py", line 2, in a
    print x
NameError: global name 'q' is not defined

EXPECTED: Traceback should say "print q" NOT "print x". It is reading from the file. Actually, the error in the file has been corrected-- it is the copy of the program in memory that is faulty.
