RuntimeError: memory access out of bounds

[ManishJu]

I am trying to compile the raytracing in a weekend which is perfectly compiling in the Xcode Here is the link to the repo I am compiling , its a simple c++ raytracer : https://github.com/ManishJu/Raytracer_2ndWeek.git Version of emscripten/emsdk: emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.61-git clang version 19.0.0git

Failing command line in full:

emcc main.cpp -O3 -o 1.html  -s WASM=1 -s ALLOW_MEMORY_GROWTH=1 -sSTACK_SIZE=10000000  && node --node-memory-debug  a.out.js

Here is the console log I am getting :

...../a.out.js:128
      throw ex;
      ^

Node.js v22.2.0

The issue is similar to issue #21848 . I tried using optimisation flag and increasing stack size but with no success
