glibc detected *** python: corrupted double-linked list

[Christian Meesters]

Hoi,

I have a problem using my software on my 64bit laptop, after an update of
my system. The same code still runs on 32bit Intel, but on my laptop I
provoke the crash in the title. The crash is caused - as narrowed down by
me - by returning a static PyObject from a C-extension function.

Well, now I wondering what to do? A web search delivered no relevant bug
reports about glibc on my system (the recent Ubuntu 8.10). Is there a
source for validated glibc for x86_64? Oh, and I'm using Ubuntu's ready-
made Python package, version 2.5.2..

Anyone experiences with such problems? Any ideas? Information missing?

TIA
Christian

PS The extension module itself can be found here: http://
svn.origo.ethz.ch/viewvc/sas-rigid/src/calc.c?revision=209&view=markup
But, as I said, the code is perhaps far from being perfect, but it runs on
32bit computers. The crash occurs at line 164 - "return py_pofr;".
