Does anyone know of memory debugging tools (like Valgrind) for native C++ code under Android NDK?

The Native Development Kit (NDK) is a set of tools that allows you to use C and C++ code with Android, and provides platform libraries you can use to manage native activities and access physical device components, such as sensors and touch input.
The Memory Profiler is a component in the Android Profiler that helps you identify memory leaks and memory churn that can lead to stutter, freezes, and even app crashes. It shows a realtime graph of your app's memory use and lets you capture a heap dump, force garbage collections, and track memory allocations.
Code written in C/C++ can be compiled to ARM, or x86 native code (or their 64-bit variants) using the Android Native Development Kit (NDK). The NDK uses the Clang compiler to compile C/C++.
We have a project that uses quite a bit of native code. As hinted in one of the comments for the question, the best approach is to test that code on another environment.
We have a separate project that builds in Linux and calls the C/C++ functions we use in our Android code. Once you are at that point, all the nice tools you are used to (gdb, Valgrind, etc.) are available to you.
A lot more productive than doing the same thing on the phone (assuming you could even find a good tool).
The tricky part is to have a good test harness, but that should be a given to any project that started off on the right path... ;)
