GLTF viewer, emscripten and build_mode

[JD31]

Hello !

(I am very beginner in the world of web assembly and emscripten compiler! )

I am able to run the GLTFViewer into chrome when I build in Debug mode with Emscripten.
But, if building exactly the same source source in Release mode (or RelWithDebInfo), it doesn't work.
There is an exception with the following stack:

GLTFViewer.html:1 Uncaught RuntimeError: memory access out of bounds

Any ideas ?

Did you try to run other applications? What about Tutorial01 and Tutorial03 in particular?

[JD31]

Yep. Both of them works well on Debug and Release mode.

Did you try to run it in another browser or platform? It is little bit hard to tell, could be browser bug or emscripten bug. Could also be a bug in the GLTF viewer, but it works fine on all other platforms.

Idem with Firefox, MS Edge and Safari.

Work well on native with MSVC in all build_modes

Maybe one thing to try is to play with compiler settings. I have seen high levels of optimization producing invalid executables.
