<pre>$ cat fallthrough.s
.globl main, _main
main:
_main:
push %rbp
main2:
call subroutine
pop %rbp
ret
subroutine:
xor %eax, %eax
ret
$ cc fallthrough.s -o fallthrough
$ lldb ./fallthrough -o 'breakpoint set -n main' -o 'process launch'
On macOS, "next / next" stops at fallthrough`subroutine instead of correctly
stepping over the call.
On Linux, "next" finishes the process instead of stepping one instruction.</pre>
