mac default iconDUMA For Mac Publisher's description

DUMA is an open-source library (under GNU General Public License)

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
