I have tried using postject to insert a small 3mb blob into node x86.

On an older windows computer, it usually gives Aborted() with no information at all, but sometimes works.
On a newer windows computer, or a mac, it always reports success, but then the exe will usually report:
FATAL ERROR: v8::ToLocalChecked Empty MaybeLocal

There is absolutely no way to verify it worked other than running the exe, which make scripting around it impossible. There are hardly any flags, not even a --version option.
What do I do other than keep running it over and over?
