Here's another example of the same thing, minus the cast/double issue. This one
is strength reduced for 3.4 but not for 4.0.

typedef struct {
  union {
    unsigned int Init[9];
    unsigned char Link[37];
  } u;
} BitStreamLinkStruct;
void f2(BitStreamLinkStruct *);

void f1 ()
{
  int  ixBlock;
  BitStreamLinkStruct bitStreamLink;

  for(ixBlock=0; ixBlock<=7; ixBlock++){
    bitStreamLink.u.Init[ixBlock] = 0x1e1e1e1e;
  }

  f2(&bitStreamLink);

}
