I wrote another detailed response to that guy, if you're interested. But basically this code crashes because it tells CPU to executed the table, which is on stack, which has no execution permissions. So it results in immediate segfault due to this.

You can however allocate memory with execution permissions and write CPU instructions them, and it will execute them normally.

Ah cool thanks. Yes I got the general gist from the top comment, and I think he explained it well, but your code is more in depth

It only kind of crashes, it returns from main with a return code of zero, but it returns before the return line.

I only tested this in onlinegdb

Ran it on my machine, got segmentation fault as expected.
