DUMA 2.5.15

Free and multi-platform memory debugger
DUMA (Detect Unintended Memory Access) is a free and multi-platform memory debugging library.

DUMA 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.

Main features:

  • "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
