Abstract

Systems, methods, and software can be used to detect software errors in a binary code. In some aspects, a method comprises: obtaining a binary code; generating a base memory-write profile for the binary code, wherein the base memory-write profile comprises a count of memory updates for each of a plurality of memory locations during an execution of the binary code according to a base input; for each of a plurality of test inputs, generating a test memory-write profile for the binary code, wherein the test memory-write profile comprises a count of memory updates for each memory location during an execution of the binary code according to the test input; comparing the base memory-write profile and the plurality of test memory-write profiles; and generating a notification based on the comparison, wherein the notification indicates whether there is a difference between the base memory-write profile and the plurality of test memory-write profiles.
