DUMA (Detect Unintended Memory Access) is a multi-platform memory debugging library. It can detect memory leaks and buffer overruns (or underruns) in a malloc() / new memory buffer. DUMA is a fork of Bruce Perens' Electric Fence library. sourceforge isn't maintained for many years! suggest you want to look at https://github.com/johnsonjh/duma

After a program has been thrown into the world in binary form, it can boomerang back as source code. The Boomerang reverse engineering framework is the first general native executable decompiler available to the public.

NB: Development has been moved to Github: https://github.com/avrdudes/avarice AVaRICE is a program for interfacing the Atmel JTAG ICE to GDB to allow users to debug their embedded AVR target.

MSPDebug is a free debugger for use with MSP430 MCUs. It supports FET430UIF, eZ430, RF2500 and Olimex MSP-JTAG-TINY programmers. It can be used as a proxy for gdb or as an independent debugger with support for programming, disassembly and reverse eng

ELFIO is a header-only C++ library intended for reading and generating files in the ELF binary format

Modern software systems and application are commonly written in multiple languages, include scripting engines, and are frequently build on multiple specialized frameworks and middleware for a considerable diversity of runtime environments. The latest influencing update in development paradigm is the application of multicore processors. This projects is aimed to unify the required trace and logging output and integrate into debugging environments. The target is to provide general development, test, and production support of software environments based on multiple programming languages for distributed multicore environments.

The "JTAG-GDB server" is a program for integrating the ARM-Embedded ICE logic with the GNU-Debugger GDB.

ISMON is a text-based monitor used to control the debug support unit embedded in the Comsis C61100/C61200 IEEE802.11n network controllers. In interactive mode ISMON accepts debug commands from the user. It can also act as a remote target for gdb.
