Problems solved by technology
[0003] At present, the main way to determine the function call information involved in the wild pointer is to reproduce the application crash scene caused by the wild pointer, so as to locate the function call information involved in the wild pointer through auxiliary tools; however, to reproduce the crash caused by the wild pointer Applying the crash scene requires a huge amount of work, the implementation logic is cumbersome, and the success rate cannot be guaranteed; therefore, how to easily and accurately determine the function call information of the wild pointer has become a problem that those skilled in the art need to consider

The embodiments of the invention provide a function stack information determining method and apparatus of a wild pointer, and an electronic device. The method comprises the following steps: hooking a memory invoking function so as to determine stack information of a memory invoking function when a memory function is invoked; determining a memory area directed by the memory invoking function, and recording the determined memory area and the stack information of the memory invoking function corresponding to the memory area; when the wild pointer causes an application crash, determining a memory area directed by the wild pointer; and determining stack information of the memory area directed by the wild pointer from the recorded memory area and the stack information of the memory invoking function corresponding to the memory area, and obtaining function stack information of the wild pointer. According to the embodiments of the invention, when the function stack information of the wild pointer is determined, the processing logic is greatly simplified, and the function stack information of the wild pointer can be more simply determined.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a method, device and electronic equipment for determining function stack information of wild pointers. Background technique [0002] A wild pointer is a pointer pointing to an unavailable memory area. If an application operates on a wild pointer at runtime, it will cause the application to crash. (The object is an instance of the class) After being released, its corresponding memory area will become an unusable memory area, and if other objects continue to use the pointer (that is, a wild pointer) while holding the pointer of the object, it will cause the application crash. In order to locate problematic codes that cause application crashes due to wild pointers, it is particularly necessary to determine the function call information involved in wild pointers. [0003] At present, the main way to determine the function call information involved in the wild pointer is to ...
