Oh yes this is introduced by Richi's extra checking for TYPE_PRECISION .

>From tree.cc:

  if (TYPE_PRECISION (subt) > TYPE_PRECISION (expt))
return exp;

Maybe type_element_precision here ...

Reduced C (and C++) code:
```
struct GdkRGBA2 {
  double a[4];
};
struct GdkRGBA3 {
  float a[4];
};
struct GdkRGBA3 f(struct GdkRGBA2 *color) {
  struct GdkRGBA3 t1;
  for(int i = 0; i < 4; i++)
t1.a[i] = color->a[i];
  struct GdkRGBA3 t2;
  for(int i = 0; i < 4; i++)
  {
float tmp = t1.a[i];
if (__builtin_isnan(tmp))
t2.a[i] = tmp;
  }
  return t2;
}

```

It is related to unord folding with convert on a vector type.

My reduction so far looks very similar.

btw, his was reduced from the same original problem but using a unity build
file

Hti5.cpp.ii

Kostadin started a reduction earlier and got this. It needs some cleaning up.
