Anything the system does that it > shouldn't do is a potential corruption problem. But is it safe to say that there are areas where a failed assert is far more likely to result in data corruption? And that there's also areas where there's likely to be difficult/impossible to find bugs, such as race conditions? ISTM that it would be valuable to do some additional checking in these critical areas. -- Jim C.
