Does memory leak? (1995)
Another "works because it's in a missile and only has to run for as short time" story:Electronics components for trajectory tracking and guidance for a particular missile weren't running fast enough, namely the older CPU that the software was targeting.  The solution to this was to overclock the CPU by double, and redirect a tiny amount of the liquid oxygen that happened also to be used in the propellent system to cool down the electronics.This apparently worked fine - by the time the missile ran out of LOX and the electronics burned themselves out, it was going so fast on a ballistic trajectory that it couldn't be reasonably steered anyway.The telemetry for the self destruct was on a different system that wasn't overclocked, in case of problems with the missile.
