I need to put recursive data structures on disc and found out that cPickle doesn't like recursion.

What are my options? alex Christian Tismer had the kindness to look at my code and point out that I might want to use pickle instead of cPickle, at least if I wanted to benefit from using stackless. Chaning from cPickle to pickle allowed to run the code under stackless as well as under standard python. thanks Christian.

Although I'm happy that things work even without Stackless, this implies that there is an incompatibility between pickle and cPickle. If objects are treated identically by both, that normal Python must use even more stack space for recursive objects that cPickle, so I'd expect it crashes earlier.

But it doesn't crash. cPickle must have a bug.
