A software bug is a design defect in computer software.A computer program with many or serious bugs may be described as buggy.. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing).

A major component of a bug tracking system is a database that records facts about known bugs. Facts may include the time a bug was reported, its severity, the erroneous program behavior, and details on how to reproduce the bug; as well as the identity of the person who reported it and any programmers who may be working on fixing it.
Mantis Bug Tracker is a free and open source, web-based bug tracking system. The most common use of MantisBT is to track software defects . However, MantisBT is often configured by users to serve as a more generic issue tracking system and project management tool .
In programming languages such as C or assembly, bugs may cause silent problems such as memory corruption, and it is often difficult to see where the initial problem happened. In those cases, memory debugger tools may be needed. In certain situations, general purpose software tools that are language specific in nature can be very useful.
In a language that supports formal exception handling, a graceful exit may be the final step in the handling of an exception. In other languages graceful exits can be implemented with additional statements at the locations of possible errors.
Using these exceptions to handle specific errors that arise to continue the program is called coding by exception. This anti-pattern can quickly degrade software in performance and maintainability. Executing code even after the exception is raised resembles the goto method in many software languages, which is also considered poor practice.
In computer programming, several language mechanisms exist for exception handling. The term exception is typically used to denote a data structure storing information about an exceptional condition. One mechanism to transfer control, or raise an exception, is known as a throw; the exception is said to be thrown. Execution is transferred to a catch.
