[New-bugs-announce] [issue1642] segfault when deleting value member in ctypes types

[Carl Friedrich Bolz]

New submission from Carl Friedrich Bolz:

When trying to delete the .value member of ctypes simple types my python
interpreter segfaults:

$ python
Python 2.5.1 (r251:54863, Oct  5 2007, 13:36:32)
[GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from ctypes import c_long
>>> c = c_long(1)
>>> c.value
1
>>> del c.value
Segmentation fault (core dumped)


Admittedly there is no good usecase for this, but it should raise an
exception and not segfault.
