What happens when a fault occurs during stack unwinding on Windows?

Question

What happens when a fault occurs during the SEH stack unwinding on Windows? For example, if the unwind info is corrupted or incorrect, or the stack has been overwritten with invalid data, and a GP fault occurs during the unwind process?

Is the diagnostic dialog still presented to the user or is there a different behavior in this case?
