I have tracked this down to a point where I don't know what to do. The problem is that the debug iterator calls consumeNext on it's theChildren, which is an eval iterator. (debug_iterator_impl.cpp:169). If this eval iterator raises a runtime exception (for example, an invalid expression like the one shown in the comment above) in eval.cpp:198, while calling: state->thePlanWrapper->next(result), the execution jump out of EvalIterator::nextImpl without calling state->thePlanWrapper = NULL; in eval.cpp:203.
Therefore a second call to the same eval iterator will fail in eval.cpp:187 at "=" (something that has to do with an RCObject that calls ~PlanWrapper. What I don't know is how to simulate state->thePlanWrapper = NULL; from a catch outside the caller of the eval iterator's nextImpl Assigning to Markos. ** Changed in: zorba Assignee: Gabriel Petrovay (gabipetrovay) => Markos Zaharioudakis (markos-za) -- You received this bug notification because you are a member of Zorba Coders, which is the registrant for Zorba. https://bugs.launchpad.net/bugs/914655 Title: XQDB: Assertion `str.size() == length' failed.
