  • Patent number: 11481307
    Abstract: For the purpose of reproducing a call stack accurately without restricting the range of application, a stack scanner extracts, from a stack area of a thread whose call stack is to be acquired in a memory space of an application process, possible return addresses that are addresses in a feasible region in the memory space each representing a command right after a function call command. A program analyzer analyzes a control flow representing a flow of control configured by a branch in a function that is called by the function call command right before the command represented by each of the possible return addresses and, when there is a route reaching a command currently being executed in the control flow, determines that the possible return address is a return address and, when there is not the route, determines that the possible return address is not a return address.
