Debugging is the process of finding and reducing the number of bugs in computer software and electronic hardware. When a program crashes, the debugger shows the position in the original code. A good debugger plays an essential role in software development.
Debugging can be more difficult when various subsystems are tightly coupled, as changes in one may cause bugs to appear in another.
This article examines three different types of debuggers: source-level debuggers and memory debuggers. Bug tracking software are covered in our Issue Tracking roundup.
A memory debugger is a programming tool for finding memory leaks and buffer overflows. These are due to bugs related to the allocation and deallocation of dynamic memory. Programs written in languages that have garbage collection, such as managed code, might also need memory debuggers.
Here’s a legendary LinuxLinks-style ratings chart capturing our recommendations. All of the software featured here are free and open source goodness.
