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

SETEdit is a friendly text editor. It is a text mode application with windows, buttons, mouse support, etc. The main target of the project are programmers so the editor is mainly oriented to programming.

The ECLiPSe Constraint Logic Programming System is designed for solving combinatorial optimization problems, for the development of new constraint solver technology and their hybrids, and for the teaching of modelling, solving and search techniques.

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.

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.

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

Camelia is an IDE for OCaml designed with students and new users in mind. It sports syntax highlighting, tool-tip type checking, clickable error explanations, an integrated debugger, and more.

RHIDE is an integrated development environment with inetgrated debugger GDB

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

A retargettable micro-controller and embedded system emulator architecture, providing common supports to emulate various types of micro-processors & devices on an x86 PC. Development of emulation for Arduino and various shields is just about to be launched in 2012.

Main features: wxHatch is a cross platform IDE for wxWigets. It generates new wxWidgets projects, with a main frame and text or drawing/imaging window, provides a simple code editor with syntax highligthing, generates makefiles for

BuGLe combines a graphical OpenGL debugger with a selection of filters on the OpenGL command stream. The debugger allows viewing of state, textures, framebuffers and shaders, while the filters allow for logging, error checking, video capture and more.

Tool for monitoring of OCI client applications [f.e.: TOAD/TOra, or any OCI-based fat client] interaction with Oracle Database. Monitors SQL statements and values passed/fetched between client application and RDBMS. Consists of simple and nice GUI [C#] and events handler [C++] with quite a lot of OCI hacking. Interface between handlers and tool's GUI is through tailing of XML "pipeline" files in $HOME/.ocimonitor directory. Tool is quite similar to Quest SQLMonitor, which is unable to trace values.

Warning: Older projects may have to be compiled with -DDEBUG_NEW_CONFIG_HAVE_DEPRECATED Debug_New offers the possibility of debugging memoryleaks, not only (note the "not only"; that's just one of its functions) in a <report-memory-leaks-on-shutdown> kind of way, but implemented using memory-states. - Cross platform + Cross compiler support (only utilizes the preprocessor and template-voodoo-magic for c++) - Supports C and C++ - Supports gcc and g++ - Supports pthread and any posix platform - Multithreading is supported. - Easy to use and install (just include the header and link the source). - Easily debug memory-leaks. - Easily debug dangling pointers. - Easily debug deallocation method correctness. - Easily debug array index errors (when writing past the end). - Easily profile memory usage and track down memory hawks. - Click-And-Goto-Source support for Visual Studio. - Integrated compatibility for new, new[], delete, delete[], malloc, calloc, realloc, free

GDBShell is FREE simplest graphical frontend for GDB (Gnu DeBugger), working under Win32. This tool is very light weight, but made GDB more usable for you.

Libinstrument is a complete and easy way to do custom function instrumentation for C/C++. The project comes ready with classic applications of instrumentation, such as AOP (Aspect Oriented Programming), Concern and Side Effect injection, stack tracing, exception tracing, basic time profiling, callgraph profiling and other. A GC (Garbage Collector) module is also under development. Libinstrument is highly portable and decoupled. The project comes with a CMake build system, integration with IDEs (CLion, Eclipse e.t.c) is straightforward. Using lazy algorithms there is virtually zero overhead in benchmarks and minimum overhead in execution time. Libinstrument tries to be as non-intrusive as possible, while trying to help the developer offering basic reflection. There are Unit Tests for each class and method, testing is driven with CTest.

rngcc is "really nice GNU C compiler" it's the GUI for the standard GCC on Unix systems rngcc is fully written in c

Trivial GDB (tgdb) is a library for making front ends to GDB using a simple API. Included with tgdb is a lightweight, but fully functional curses front end called cgdb.

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.

UPS is a source level C, C++ and Fortran debugger with an X windows interface. It's a very light debugger, but is quite efficient and works well. An ANSI compliant C interpreter is included.

Mickey is a hex/ascii file viewer and editor that runs on all major operating systems thanks to FLTK.
