ANALYSIS SYSTEM, ANALYSIS METHOD, AND COMPUTER PROGRAM PRODUCT

According to an embodiment, a system includes an analysis generator, a trace difference generator, a program difference generator, and an analyzer. The analysis generator is configured to generate program information required in executing a program, generate trace information providing a description of an execution at particular timing, based on the program information, and generate a trace correspondence between the trace and program information. The trace difference generator is configured to generate a trace difference between first and second trace information. The program difference generator is configured to generate a program difference between first and second program information. The analyzer is configured to analyze a correspondence relation between the differences and the program information based on the trace correspondence.
