=====  Debugger  =====

A //debugger// is a tool used to analyze running code.

Although debugging tools are available for interpreted and bytestream languages, the term //debugger// is often used to describe a tool that can analyze object code.

Typical features of a debugger include:
  *  the ability to [[Disassembler|disassemble]] code
  *  the ability to cross-reference and display source code and address [[Symbol|symbols]] (for functions and variables)
  *  the ability to execute single instructions or lines of code (single-step)
  *  the ability to stop execution at a requested location in the program (breakpoint) or when a variable changes value (watchpoint)
  *  the ability to trap and examine faults (such as a segmentation fault)
  *  the ability to examine variables and [[Register|registers]]

The GNU debugger is named "gdb" and has a command-line interface. Various graphical front-ends are available.
