Description

If the first 4 bytes of the checkpoint are overwritten, then the current sanity check will miss it because we read the first long and then cast it to an int, missing the first 4 bytes when we check the version. First 4 bytes being corrupt could indicate further corruption in the checkpoint which cannot be verified because the remaining data consists mostly of pointers to files, which if not used are simply ignored by the replay mechanism
