Dmalloc
Encyclopedia
Dmalloc is a memory debugger
C
library, written by Gray Watson, that helps programmers to find a variety of memory allocation programming errors for dynamic memory. It replaces parts of standard programming library provided by the operating system
for malloc
and other software with its own versions which help the programmer detect buffer overflow
s and other critical programming issues.
Dmalloc can find memory leaks, off-by-one error
s, usage of invalid addresses in some library functions calls.
Memory debugger
A memory debugger is a programming tool for finding memory leaks and buffer overflows. These are due to bugs related to the allocation and deallocation of dynamic memory. Programs written in languages that have garbage collection, such as managed code, might also need memory debuggers, e.g...

Buffer overflow
In computer security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory. This is a special case of violation of memory safety....

Off-by-one error
An off-by-one error is a logical error involving the discrete equivalent of a boundary condition. It often occurs in computer programming when an iterative loop iterates one time too many or too few...
