--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

Easier testcase:
```
#define size 129
struct
{
  _BitInt(size) a : size;
  _BitInt(size) b : size;
} bf;

int
foo (void)
{
  return bf.b;
}
```

Note changing the bitfield size down to below 128 allows the above not to ICE.
