1. A computer-implemented method of diagnosing a fault condition comprising: marking a fault condition, identifiable by call-stack information corresponding to the fault condition, resolved for a particular release of a software; responsive to detecting a subsequent fault condition, receiving, within a computer system, subsequent call-stack information for the subsequent fault condition that matches the call stack information for the fault condition that has been marked resolved; and determining, by the computer system, that the subsequent call-stack information indicates a fault condition that is unrelated to the fault condition that was marked resolved.
