[New-bugs-announce] [issue20115] NUL bytes in commented lines

[Armin Rigo]

New submission from Armin Rigo:

This is probably the smallest example of a .py file that behaves differently in CPython vs PyPy, and for once, I'd argue that the CPython behavior is unexpected:

   # make the file:
   >>> open('x.py', 'wb').write('#\x00\na')

   # run it:
   python x.py

Expected: either some SyntaxError, or "NameError: global name 'a' is not defined".  Got: nothing.  It seems that CPython completely ignores the line that is immediately after a line with a '#' and a following '\x00'.
