According to the Solidity 0.8.17 compiler (200 optimization runs) 

    // What does C.g() return?

contract C {
  struct S {
    uint x;
  }

  function f(S memory s) private pure {
    s.x = 2;
  }

  function g() external pure returns (uint) {
    S memory s;
    s.x = 1;
    f(s);
    return s.x;
  }
}

Hint:

A memory object passed into a function taking a memory parameter will pass it in by reference.
