[pypy-issue] [issue1266] Popping and appending to range causes Fatal RPython error

[Brian]

New submission from Brian <thefollowingcanbefound at gmail.com>:

The following code causes Fatal RPython error: IndexError.
d = range(1)
d.pop()
d.append(1)

>From what I can tell the exception is always thrown if a range is popped until empty and then append 
is called with any argument.  I have observed this behavior on both 1.8 and 1.9.  No exception is 
thrown by cPython 2.7.3.  Replacing the first line with "d = list(range(1))" does not prevent the 
exception, but "d = [x for x in range(1)]" does.

Here is the raw output running the attached file (same as code above).
