1. A computing device for identification of a potential root cause of a use-after-free memory corruption bug of a program, the computing device comprising: a memory allocation module to compile the program with a least recently used (LRU) memory allocator; a replay module to replay execution of the program in response to compilation of the program and based on an execution log of the program, wherein the execution log comprises an ordered set of executed instructions of the program that resulted in the use-after-free memory corruption bug; a corruption candidate identification module to (i) compare a use-after-free memory address access of the program to a memory address associated with an occurrence of the use-after-free memory corruption bug in response to detection of the use-after-free memory address access and (ii) record, to a candidate list, the use-after-free memory address access of the program as a candidate for a root cause of the use-after-free memory corruption bug in response to detection of a match between the use-after-free memory address access of the program and the memory address associated with the occurrence of the use-after-free memory corruption bug.
