toolchain@gentoo.org Gentoo Toolchain Project Valgrind is a GPL'd tool to help you find memory-management problems in your programs. When a program is run under Valgrind's supervision, all reads and writes of memory are checked, and calls to malloc/new/free/delete are intercepted. As a result, Valgrind can detect problems such as - Use of uninitialised memory - Reading/writing memory after it has been free'd - Reading/writing off the end of malloc'd blocks - Reading/writing inappropriate areas on the stack - Memory leaks -- where pointers to malloc'd blocks are lost forever - Passing of uninitialised and/or unaddressible memory to system calls - Mismatched use of malloc/new/new [] vs free/delete/delete [] - Some abuses of the POSIX Pthreads API cpe:/a:valgrind:valgrind
