RefDbg is a GObject reference count debugger.
Since C lacks garbage collection, a reference counting system is used. Each object has a count of how many other references (pointers) there are to it. Reference count bugs can be very hard to track down and can lead to crashes and memory leaks. Refdbg is a tool that can be used interactively with GDB to log, display and break on reference count activity, thereby making this task easier.
