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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Call stack acquisition device, call stack acquisition method and call stack acquisition program","description":"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 mem","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11481307","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
