AWS Lambda is a serverless compute service that can run code in response to predetermined events or conditions and automatically manage all the computing resources required for those processes. Customizing and connecting these services requires code. What is AWS Lambda? Where does Lambda fit in the AWS ecosystem?

In order to understand “segmentation fault,” it is a must to know the basic idea of segmentation and its implementation in C programming. When we need to execute any program, it should be loaded into memory first. Here, memory is divided into equal sizes of partitions where the code of a program resides.

The problem is that this system has a default libc that has been compiled without frame pointers, so any stack walking stops at the libc layer, producing a partial stack that's missing the application frames. Apart from library code, maybe your application doesn't have frame pointers either, in which case everything is broken.

Ideally the CPU goes to sleep when Sleep(1) is called, in order to save power, so how does the operating system (OS) wake your thread if the CPU is sleeping?
