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