Also basic:  run hardware CPU and memory stress diagnostics, and/or try running the same thing on a different machine.  Hardware isn't infallible, and can fail in nearly arbitrary ways.  For example, perhaps a smidgen of silicon has gone flaky, so that one time in a billion bit 0 "leaks" into bit 1 in a register.  That can effectively change the integer 1 to the integer 2.

Is that likely?  No.  But a loop doing mutually inconsistent things to the variables it's changing is impossible ;-)
