Post-mortem Debugging with Core Dumps
Learn to analyze core dumps and crash reports to debug issues that occurred in the past, without live access.
Debugging After the Fact
Welcome! In this lesson, we'll explore post-mortem debugging. This powerful technique lets you investigate software failures after they've occurred, without needing to reproduce the issue live.
It's incredibly useful when you can't attach a debugger directly to a crashing application, especially in production environments.
What's a Core Dump?
The cornerstone of post-mortem debugging is the core dump. Think of it as a snapshot of a program's entire memory space and CPU state at the exact moment it crashed.
- It's a file generated by the operating system.
- It contains critical information about the program's execution.
- It helps you understand why a crash happened.
