Help building dlib example using opencv to js (Emscripten)

Have been trying to convert dlibs facial landmarks code to js using emscripten. It fails in parts where it has been using OpenCV where it uses the native c++ libraries instead of Emscripten libcxx libraries. There's an issue on Emscripten I have issued and have got some help from them - https://github.com/kripken/emscripten/issues/5435. I had even tried building opencv from source using Emscripten option as defined in its CMakelists.txt.

Need to get some help about what could be the procedure I may go about to tackle this. Any help will be appreciated.

Update: Was able to build and install OpenCV from source for EMSCRIPTEN. Tried to compile the dlib code to js which resulted in an error like

/home/akshay/Downloads/emsdk-portable/emscripten/1.37.19/build.emscripten/DLIB.js:110
      throw ex;
      ^
Runtime error: The application has corrupted its heap memory area (address zero)!

While building the code it generated warnings like :

warning: emitted code will contain very large numbers of local variables, which is bad for performance (build to JS with -O2 or above to avoid this - make sure to do so both on source files, and during 'linking')
