[issue17735] inspect.findsource throws IndexError

[Kyle Simpson]

New submission from Kyle Simpson:

Here is one way to reproduce this bug:

1. Create a module file (bug.py in this example)

def func():
    pass

2. Run Python

>>> import bug
>>> help(bug)

3. Edit bug.py

def func():
    pass

def newfunc():
    pass

4. Use the same Python interpreter as in step 2

>>> reload(bug)
>>> help(bug)

5. Observe traceback

  [..snip..]
  File "C:\Python27\lib\inspect.py", line 578, in findsource
    if pat.match(lines[lnum]): break
IndexError: list index out of range
