Check on the Therac-25 case, whis is particularly scary for me, having worked for 10 years on medical software (on the sysadmin side).

A race condition which killed people: https://en.wikipedia.org/wiki/Therac-25

> It was involved in at least six accidents between 1985 and 1987, in which patients were given massive overdoses of radiation. Because of concurrent programming errors, it sometimes gave its patients radiation doses that were hundreds of times greater than normal, resulting in death or serious injury.
