PROBLEM TO BE SOLVED: To perform sufficient evaluation including back trace analysis by carrying out trace output before and after receiving a system call from an application program(AP). SOLUTION: This device is provided with an AP 11 as a program for performing prescribed processing and an operating system(OS) 12 as a program for managing the execution of AP 11. When there is a system call from the AP 11 to the OS 12 in the case of executing that AP 11, upon receiving a system call, a trace output means 12a performs the back trace analysis for extracting information stacked in the register or memory of a CPU, performs trace output before the point of time and also continuously performs trace output after the point of time. Then, a debugger 13 converts the result of trace output obtained by the trace output means 12a and outputs it as the information of symbolic format.
