[OxLUG Announce] Valgrind - Julian Seward - Sunday 1st Sept 6.30pm

[Alasdair G Kergon]

Valgrind: An Open-Source Memory Debugger for x86-linux - Julian Seward

Valgrind is a GPL'd tool to help you find memory-management problems
in your programs. You can use it to debug more-or-less any
dynamically-linked ELF Linux x86 executable, without modification,
recompilation, or anything. It works by translating x86 code to
instrumented x86 code, on the fly i.e. a virtual machine.  Valgrind
can detect problems such as:

    * Use of uninitialised memory;
    * Reading/writing memory after it has been free'd;
    * Reading/writing off the end of malloc'd blocks;
    * Reading/writing inappropriate areas on the stack;
    * Memory leaks - where pointers to malloc'd blocks are lost forever;
    * Passing of uninitialised and/or unaddressible memory to system calls;
    * Mismatched use of malloc/new/new [] vs free/delete/delete [].

Julian Seward is a Compiler hacker and open-source contributor. 
Worked recently on the Glasgow Haskell compiler, GHC, which is under a
BSD-style license. Also the author of bzip2 (data compressor),
cacheprof (a tool for locating the sources of D-cache misses).
