Bug Description

Binary package hint: python-cdb

This patch fixes segfaults caused by python-cdb in Python 2.5. I got it from Gentoo's python-cdb package. It appears that PyObject_DEL is the correct API whereas python-cdb is using PyMem_DEL instead.

Note that this is very similar to bug #115655. Applying the patch might also solve bug #157251.

Hi Shane,
thanks for reporting this bug and for working on a fix.
However I'm not sure if this bug is still reproducible with the latest version of python-cdb, can you please try to reproduce this bug with an updated installation of your ubuntu system.
If this bug is still reproducible, can you please:
* add detailed information about your system (version of ubuntu, version of python and python-cdb etc.)
* add detailed information on how to reproduce this segfault (e.g. sample code)

Thanks in advance,
Markus

Markus,

I no longer have access to the system where it was failing, so I can not reproduce it anymore.

The issue remains that the package is using the wrong API and the upstream maintainer seems to be MIA. Since about Python 2.0, PyObject_Del, not PyMem_Del, is the correct API for most users of the Python C API. If PyMem_Del happens to be working, it's an undocumented accident.
