A commercial performance profiler and memory debugger for Linux applications.

Carillon is a system for finding Y2K problems in C programs

Coretrace is a tool for debugging of embedded Linux applications. It works by analysing core files from crasched applications.

Fuzz is a tool for testing other software. It does this by bombarding the program being evaluated with random data.

Insight is a graphical user interface to GDB, the GNU Debugger written in Tcl/Tk by people working at Cygnus Solutions.

Calltree tool for c like cflow

Leaky can help you track down memory leaks and some kinds of memory corruption. It also has entry pointers for logging addref / release calls. The key thing that leaky does is this: it logs all calls to malloc / free / realloc / new / delete into a log file. The logging data includes information about size and address, as well as the call stack of the operation. The leaky program then can translate the call stack data from addresses into symbols and then dump the data out.

Open source, kernel-level debugger for Linux with the look and feel of Window's SoftIce

The Linux Trace Toolkit catalogs system events in minute detail, and allows a user to determine exactly what is transpiring on his system, down to the microsecond.

A toolkit for constructing program analyses such as dataflow and type inference systems. Program analyses are widely used in compilers and software engineering tools for discovering or verifying specific properties of software systems, such as type safety and opportunities for program optimization.

Cxref is a program that will produce documentation (in LaTeX, HTML, RTF or SGML) including cross-references from C program source code. It works for ANSI C, including most gcc extensions. The documentation for the program is produced from comments in the code that are appropriately formatted. The cross referencing comes from the code itself and requires no extra work.

This kernel allows developers to write and debug code using the normal process-level tools, like gdb, gprof, and gcov.

An open-source memory debugger for x86-linux.

Experimental patches for valgrind to support memory pool-based custom allocators.

Three experimental tools for Valgrind; a heap profiler, a pointer misuse-checker, and a signal-handler checker. Additionally an experimental Valgrind distribution that has an interactive command line.

viewcore - coredump debugging software which works on Linux(ELF) and Mac OS X(mach-o). It helps the programmer to obtain essential information about the abnormal termination of a process or a thread.
