It provides\nthe same features as the original (poison freed memory, detect heap overruns\nand underruns), except that it provides more debugging information whenever it\ndetects a problem.\n\nIn addition to the original features, the new chk_malloc() implementation\ndetects multiple frees within a given range of the last N allocations, N being\nconfigurable via the system property libc.debug.malloc.backlog.\n\nFinally, this patch keeps track of all outstanding memory allocations.  On\nprogram exit, we walk that list and report each outstanding allocation.\n\n(There is support (not enabled) for a scanner thread periodically walks over\nthe list of outstanding allocations as well as the backlog of recently-freed\nallocations, checking for heap-usage errors.)\n\nFeature overview:\n\n  1) memory leaks\n  2) multiple frees\n  3) use after free\n  4) overrun\n\nImplementation:\n\n-- for each allocation, there is a:\n  1) stack trace at the time the allocation is made\n  2) if the memory is freed, there is also a stack trace at the point\n  3) a

allocations what are freed; when you call free(), instead of\n     actually freed, the allocation is moved to this backlog;\n  4) when the backlog of allocations gets full, the oldest entry gets evicted\n     from it; at that point, the allocation is checked for overruns or\n     use-after-free errors, and then actually freed.\n  5) when the program exits, the list of outstanding allocations and the\n     backlog are inspected for errors, then freed;\n\nTo use this, set the following system properties before running the process or\nprocesses you want to inspect:\n\nlibc.malloc.debug.backlog # defaults to 100\nlibc.malloc.debug 10\n\nWhen a problem is detected, you will see the following on logcat for a multiple\nfree:\n\nE/libc    ( 7233): +++
