D.U.M.A. - Detect Unintended Memory Access (original) (raw)

DUMA is an open-source library (under GNU General Public License) to detect buffer overruns and under-runs in C and C++ programs.
This library is a fork of Buce 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 defectice 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
• runs on Linux / U*ix and MS Windows NT/2K/XP operating systems
• preloading of the library on Linux (and some U*ix) systems allowing tests without necessity of changing source code or recompilation Following article - in german - was printed in the magazine "Programmieren unter Linux 1/2005 (1)":
