These errors are due to a bit or two being flipped in either the long or
double representation of the number. They could be due to a compiler
bug, but other potential culprits include bad memory, a bum power supply
introducing noise, or cooling problems.
Has your colleague run memtest86 or other load tests for a day on their box?
