Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0025] It will be understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, the first task stack may be referred to as the second task stack, and similarly, the second task stack may be referred to as the first task stack, without departing from the scope of this application. Both the first task stack and the second task stack are task stacks, but they are not th...

Abstract

The invention relates to a stack overflow detection method and device, computer equipment and a storage medium. The method comprises the steps that an accessed task stack is determined as a first taskstack, the attribute of the first task stack is a read-write permission attribute, and the attributes of other task stacks except the first task stack are all non-access permission attributes; and when it is detected that access exceeds the first task stack, stack overflow prompt information is generated, and the stack overflow prompt information is used for prompting that stack overflow exists in the first task stack. By adopting the method, the stack overflow condition can be detected more comprehensively.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a stack overflow detection method, apparatus, electronic device, and computer-readable storage medium. Background technique [0002] Stack is an abstract data structure, which is a combination of a group of the same data type. All operations are performed at the top of the stack, with the characteristics of "last in, first out", that is, the last object placed on the stack is always Take it out first. [0003] There are generally many tasks running in an embedded system, and each task will allocate a small piece of memory as a stack to store data such as return addresses, input parameters, and local variables. During the running of the system, if the allocated stack is insufficient for various reasons, a stack overflow phenomenon will be formed, which will destroy the adjacent memory space. If this behavior is not reported in time at this time, it will have a g...
