segfault

In the world of software development, particularly in systems programming, understanding how an application behaves under erroneous conditions, such as memory access violations, is crucial. This typically involves exploring how your program responds to various signals such as a segmentation fault (SIGSEGV). In this article, we will explore how to intentionally trigger a segmentation fault in a Bash script to test signal handling mechanisms. Q: What is a segmentation fault? A: A segmentation fault (often abbreviated as segfault) is a specific kind of error caused by accessing memory that “does not belong” to you. It's a way your program tells you that you are attempting to access memory in a way that is not allowed.
