It is related though.
Reduced testcase:
```
typedef struct {
bool : 1;
} a;
typedef struct {
bool b;
a e;
} c;
typedef struct {
a e;
bool d;
} g;
typedef struct {
union {
c data;
g continuation;
};
} f;
void h() {
g i = {.d = h};
f a = {.continuation = i};
}
```
Note the above testcase only ICEs with checking enabled (-O2 -fchecking).
the struct a was originally:
```
typedef struct {
bool _reserved : 1;
uint32_t identifier : 31;
} Http2Identifier;
```
Note the original testcase also ICEs without checking, let me try to reduce
that too.
