@damaneice and I tried a lot of different configurations. The reason this is happening has something to do with the _compile_array internals and the problem is solved using emscripten 1.38.32+ and adding the flag -Os or -Oz (https://emscripten.org/docs/optimizing/Optimizing-Code.html#optimizing-code-size) to the emcc call when building the WASM.

To fix this we added that flag here https://github.com/jasoncharnes/run.rb/blob/master/src/emscripten/ruby-2.6.1/Dockerfile#L23
