If you build with `-g` (or just `--profiling-funcs`) when you should see symbol names in your backtrace which might help you figure out what is going on. You might also want to drop the `-O3` when debugging too.
BTW, we have `emscripten_console_log` and `emscripten_console_error` functions so you shouldn't need to write EM_ASM blocks just to write to the console.
