You can use wasm-objdump or wasm-dis to see the actual data in the data section.. and maybe somehow create a diff. Or at least you might be able to visually what data exists there.
However, my first piece of advice you be to upgrade from 1.38.28. That version is extremely old now by emscripten standards and a lot has changed since then. It will be easier to support you if you can upgrade to a 2.0.X version.
