Automatic Memory Leak Tracking on Android

Android provides a mechanism to track memory leakage.
In folder bionic/libc/bionic/malloc_leak.c is compiled into /system/lib/, it is a memory leakage tracking version of To enable the memory leakage tracking, replace the /system/lib/ with the /system/lib/
> adb shell mv /system/lib/ /system/lib/
> adb shell mv /system/lib/ /system/lib/
Before doing that, be sure to remount the system partition to 'rw'.
Use 'mv' command may have problem without, in that case use 'cp' command instead.
With the memory leak tracking, you shall see something like "MALLOC_DEBUG = 1 (leak checker)" in your logcat output.

I have one question about memory leak detection:
1. Does "MALLOC_DEBUG = 1 (leak checker)" indicate that
a) there is a memory leak or
b) these is a malloc( )

From my test restul, the answer seems to be (b) theis is a malloc(). If that is the case, how could we locate the exact memory leakage?
