My wild guess would be there is a reference cycle being introduced into an SA expression language structure that is causing the compiler's visitor code to chase its tail. I don't know if the compiler does cycle detection, if so perhaps this is a corner case that is getting past it. In addition to needing to see the query that's causing this, the top of the stack trace seems to be missing also, Johnathan. I don't see any stack frames from your app code. -Kyle --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
