It seems like you are using a different definition of undefined
behavior than what I understand it to be. UB is not a useful symptom
because it can be anything, and can vary by implementation. It
doesn't necessarily mean the program crashes, it could for example
result in exactly the harmless unnoticed response to a bug you object
