This sounds like corrupt data --- specifically, 1664639562 showing
up where a variable-width field's length word ought to be. It
may or may not be relevant that the ASCII equivalent of that bit
pattern is Jb8c ... do you work with data that contains such
substrings?

If it's not 100% repeatable I'd start to wonder about flaky hardware.
Have you run memory and disk diagnostics on this machine recently?
