Diagnoses run-time errors

'mpatrol' is a link library that diagnoses run-time errors caused by the wrong use of dynamically allocated memory, including writing to free memory and memory leaks. It provides a configurable log of all dynamic memory operations (such as malloc(), operator new, etc.) that occurred during the lifetime of a program, checks to detect misuse of dynamically allocated memory, and has support for both memory allocation profiling and tracing. Users can change the library settings at run-time via an environment variable without recompiling or relinking.
