Detect Unintended Memory Access - A Red-Zone memory allocator

Description

Open-source library to detect buffer overruns and under-runs in C and C++ programs.

This library is a fork of Bruce Perens Electric Fence library and adds some new features to it. Features of the DUMA library:
  * "overloads" all standard memory allocation functions like
    malloc(), calloc(), memalign(), strdup(), operator new, operator
    new[] and also their counterpart deallocation functions like free(),
    operator delete and operator delete[]
  * utilizes the MMU (memory management unit) of the CPU:
    allocates and protects an extra memory page to detect any illegal
    access beyond the top of the buffer (or bottom, at the user's option)
  * stops the program at exactly that instruction, which does the
    erroneous access to the protected memory page,
    allowing location of the defective source code in a debugger
    detects erroneous writes at the non-protected end of the memory
    block at deallocation of the memory block
  * detects mismatch of allocation/deallocation functions: f.e.
    allocation with malloc() but deallocation with operator delete
  * leak detection: detect memory blocks which were not deallocated
    until program exit
  * preloading of the library
  * allowing tests without necessity of changing source code or recompilation
