--- Comment #17 from Walter Bright <bugzi...@digitalmars.com> ---
On Linux x86, given the code:

  struct S { };
  int test(S s, int a) { return a; }

g++ produces:
    mov EAX,8[ESP]
    ret

while clang++ produces:

    mov EAX,4[ESP]
    ret

This is with optimization on. With it off, the same problem.
