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

[Christian Meesters]

Thanks David!

It's still not debugged, but indeed: I get a bunch of warnings. And this 
already showed me that there are more potential problems than my first 
guess indicated. Alas, for my specific problem I cannot work with ints 
chars and doubles. I need to have unsigned longs at some points.

Well, I'll sort it out.

Cheers
Christian
