[New-bugs-announce] [issue17715] Raising an exception in __trunc__ gives a segmentation fault.

[Mark Dickinson]

New submission from Mark Dickinson:

Python 3.4.0a0 (default:838fdf3bb0c6, Apr 13 2013, 16:54:22) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> class A:
...     def __trunc__(self): 1/0
... 
>>> int(A())
Segmentation fault

It looks as though the problem is in PyNumber_Long, where there's an unchecked return value for PyEval_CallObject.
