Here is a testcase which I can reproduce it with on powerpc-darwin (it just has 
more elements in the 
struct):
struct fn_hash_idx_t {
  unsigned datum;
  unsigned datum2;
  unsigned datum3;
  unsigned datumi4;
  unsigned datum5;
  unsigned datum6;
  unsigned datum7;
  unsigned datum8;
  unsigned datum9;
};

struct fn_hash_idx_t
fn_hash(unsigned h)
{
  return *(struct fn_hash_idx_t*)&h;
}
