This might be a dupe of PR114918 but figured I'd keep it separate in case it
isn't.

```

--- Comment #2 from Sam James <sjames at gcc dot gnu.org> ---
Reduced:
```
typedef struct cl_lispunion *cl_object;
struct cl_lispunion {};
cl_object cl_error() __attribute__((noreturn));
static void L250safe_canonical_type(cl_object volatile) { cl_error(); }
volatile cl_object _eclqGeUMgTYTtUr9_moBRo471_env0;
```

so a dupe
