9 Valgrind is a GPL'd tool to help you find memory-management problems
10 in your programs. When a program is run under Valgrind's supervision,
11 all reads and writes of memory are checked, and calls to
12 malloc/new/free/delete are intercepted. As a result, Valgrind can
13 detect problems such as
15 - Use of uninitialised memory
16 - Reading/writing memory after it has been free'd
17 - Reading/writing off the end of malloc'd blocks
18 - Reading/writing inappropriate areas on the stack
19 - Memory leaks -- where pointers to malloc'd blocks are lost forever
20 - Passing of uninitialised and/or unaddressible memory to system calls
21 - Mismatched use of malloc/new/new [] vs free/delete/delete []
22 - Some abuses of the POSIX Pthreads API
