Hello libs debugging line numbers

[Mitch Besser]

I was playing with https://github.com/googlesamples/android-ndk/tree/master/hello-libs example with Android Studio and the line numbers while debugging into the C++ code seem off. 

For example, stepping into:

https://github.com/googlesamples/android-ndk/blob/master/hello-libs/gen-libs/src/main/cpp/gmath/src/gmath.c

starts executing gpower on line #37

if (n > 31) {

and not line #35 <if (n == 0)> as you would expect.

I was looking for a way to see the assembly underneath to see if I'm correct or if I just don't understand how to use the debugger. 

It would be a great help me if someone could try it on their system and see if stepping though the C++ code in both the static and shared libraries works correctly for them. I'm running on Linux if that makes any difference. 

Thanks

I found a Windows 7 system to test on, I don't see the problem there. Is this just a Linux problem? 

Can someone please confirm this is a Linux problem or is it something I don't have set up correctly? If you follow the directions and uncomment as directed in the README

https://github.com/googlesamples/android-ndk/blob/master/hello-libs/README.md

build and debug, it is easy to re-create (or confirm it works). 

Thanks.

I have tried to debug the cpp code in a module, my break-point doesn't work, it seems that if you debug cpp code in your `app` module, it works but if you debug in another module it doesn't work.

I am not a native English speaker so can you understand my words?

I appears to work if I use Windows to run an emulator. It doesn't work on Linux with an physical phone. I'm confident this is a bug, but I don't know how to report it.
