Summary: d: error overlapping initializer for bitfield with
-m32 -fpreview=bitfields
Product: gcc

Status: UNCONFIRMED
Severity: normal

```
struct T
{
uint a : 1;
union {
struct {
uint : 2;
uint c : 3;
}
}
}
```
When compiled with -m64, the anonymous bitfield has a bit offset of `0`, but
this ends up being `34359738336` on -m32.
