Package duma-2.5.15-1

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

Link programs against libduma.a or use the "duma" script to run a single executable with libduma.dylib. You can also run a program with (export LD_PRELOAD=/sw/lib/libduma.0.dylib; \ export DYLD_INSERT_LIBRARIES=/sw/lib/libduma.0.dylib; \ export DYLD_FORCE_FLAT_NAMESPACE=1; exec programname)
