Abstract

A method and system for detecting abnormal interleavings in a multi-threaded program includes generating an execution log in response to execution of the multi-threaded program. Based on the execution log, a list of allowable immediate interleavings is generated if the execution of the multi-threaded program resulted in no concurrency errors and a list of suspicious immediate interleavings is generated if the execution of the multi-threaded program resulted in one or more concurrency errors. The first and second lists are compared to generate a list of error-causing immediate interleavings. A replayable core is then generated and executed based on the list of error-causing immediate interleavings.
