Abstract

The disclosure relates to a detection method and device for a stack overflow location, which are used to quickly and easily detect the stack overflow location. The method includes: before executing the function to be tested, determining the initial value of the random initialization number in the program, wherein the random initialization number is at a byte-aligned address before the last element of the array buffer of the program; executing The function to be tested, and after executing the function to be tested, obtain the current value of the random initialization number; judge whether the current value is the same as the initial value; when the current value is the same as the initial value At the same time, it is determined that a stack overflow does not occur in the function to be tested; when the current value is different from the initial value, it is determined that a stack overflow occurs in the function to be tested. The method realizes quick and easy detection of stack overflow position.

Description

technical field [0001] The present disclosure relates to the technical field of terminal equipment development, and in particular to a method and a device for detecting a stack overflow location. Background technique [0002] With the popularity of smart phones, there has been an upsurge in mobile development in recent years, especially the open source of the android system, which has made the cost of developing mobile phone systems for various manufacturers very low, and has also attracted more and more developers. Entering this embedded field development platform, the embedded field is mainly based on the embedded development of arm architecture. arm programming and debugging technology has increasingly become the core competitiveness of today's mobile development field. Developing and debugging programs quickly is a skill that every mobile developer desperately wants to master. [0003] The stack overflow problem is very common in program development. However, programme...
