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 |
