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 ;-) |
