Abstract
A call stack acquisition device reproduces, from a memory dump, a memory space of a process to which a thread as a production target of a call stack belongs. Then, the call stack acquisition device acquires execution context of the thread by acquiring, from a virtual memory space, register information of the thread, which is stored in a memory by an OS. In addition, the call stack acquisition device acquires a current stack position and a currently executed function from the acquired execution context. Thereafter, the call stack acquisition device acquires the call stack by tracing return addresses of a series of functions as callers of the currently executed function on the stack from metadata of an execution file of the process including the thread.
