Abstract:
An information processing apparatus includes a memory and a processor. The memory stores a first string of error detection codes each corresponding to a used partial area of a stack area allocated to a program. The processor generates, when execution of the program is interrupted, a differential string of error detection codes each corresponding to a used partial area of a difference between used partial areas at the time of generating the first string and used partial areas at the interruption. The processor obtains a second string of error detection codes by reflecting the differential string to the first string. The processor generates, when the execution of the program is resumed, a third string of error detection codes each corresponding to a used partial area of the stack area at the resumption. The processor detects stack destruction based on collation between the second string and the third string.
