The debug memory allocation or "dmalloc" library has been designed as a drop in replacement for the systems `malloc, `realloc, `calloc, `free and other memory management routines while providing powerful debugging facilities configurable at runtime. These facilities include such things as memory-leak tracking, fence-post write detection, file/line number reporting, and general logging of statistics.
dmalloc for Mac OS X is the collection of patches for the dmalloc source code that enables building of the dmalloc libraries and tools on Mac OS X. Pre-built libraries and binaries for Mac OS X are not available.
