The language runtime can require that the OS & hardware always results in an exception on stack overflow (or, alternatively, compile in explicit checks for it). You running the program in an environment without that is, technically, just as wrong as running it on a system where integer addition does multiplication.

Now perhaps this means that there are real rust deployments that are "wrong", but that shouldn't include regular sane standard systems, and embedded users should know the tradeoffs.

    .LBB3_1:
            sub     rsp, 4096
            mov     qword ptr [rsp], 0
            cmp     rsp, r11
            jne     .LBB3_1

That's a loop at the start of your 'main' that probes the stack specifically to ensure a segfault definitely happens if your array didn't fit on the stack.
