Yes, since step-out is to get the previous caller and we cannot assume different libc implementations have same call stack.

I also try to create a testcase like the following:
```
void g() {}
void f() {g()}
int main() {f()}
```
and set a breakpoint on g(), step-out twice. It seems that simple program does not break lldb on FreeBSD.
