The Boehm-Demers-Weiser conservative garbage collector can be used as a garbage collecting replacement for C malloc or C++ new. It is also used by a number of programming language implementations that use C as intermediate code. Alternatively, it may be used as a leak detector for C or C++ programs. A slightly older version of the garbage collector is also included as part of the GNU compiler (gcc) distribution.
