ERROR DETECTING APPARATUS, PROGRAM AND METHOD

摘要

An error detecting apparatus includes: an execution history storing unit to store a first execution history which is an execution history of a first program, and a second execution history which is an execution history of a second program changed from said first program; a flow comparing means for extracting positions, which are determined on the basis of positions at which a difference between number of executions of a predetermined instruction to number of executions of said first program, and number of executions of an instruction corresponding to said predetermined instruction to number of executions of said second program is not smaller than a predetermined value, from said first execution history and said second execution history; and a cause position restricting means for outputting cause position information which indicates a preceding position form said position of said second program.

1. An error detecting apparatus, comprising:
an execution history storing unit to store a first execution history which is an execution history of a first program, and a second execution history which is an execution history of a second program changed from said first program; a flow comparing means for extracting positions, which are determined on the basis of positions at which a difference between number of executions of a predetermined instruction to number of executions of said first program, and number of executions of an instruction corresponding to said predetermined instruction to number of executions of said second program is not smaller than a predetermined value, from said first execution history and said second execution history; and a cause position restricting means for outputting cause position information which indicates a preceding position form said position of said second program.
