Reduced testcase:

typedef struct _OilFunctionImpl OilFunctionImpl;

struct _OilFunctionImpl {
 void *func;
};

static void
ayuv2yuyv_ref (int *d, int *src, int n)
{
  char *dest = (char *)d;
  int i;

  for(i=0;i<n/2;i++){
    dest[i*4 + 0] = (((src[i*2 + 0])>>16)&0xff);
    dest[i*4 + 1] = ((((src[i*2 + 0])>>8)&0xff) + (((src[i*2] +
1)>>8)&0xff))/2;
    dest[i*4 + 2] = (((src[i*2 + 1])>>16)&0xff);
    dest[i*4 + 3] = ((((src[i*2 + 0])>>0)&0xff) + (((src[i*2] +
1)>>0)&0xff))/2;
  }
}

OilFunctionImpl _oil_function_impl_ayuv2yuyv_ref = {(void *)ayuv2yuyv_ref};
