I disagree. Even if the new stack-overflow code works, it doesn't change the fact that a stack-overflow is a problem for the end-user and we should try to avoid causing such things. IOW, Dmitry's overflow-handling is good because it makes the failure a bit cleaner, but it's still a failure that we should strive to avoid. Stefan
