            Bug ID: 102740
           Summary: [11.2/12 Regression] Data member not found in struct
                    inside an unnamed union
           Product: gcc
           Version: 11.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: curdeius at gmail dot com
  Target Milestone: ---

Reproduce on godbolt: https://godbolt.org/z/3frPbPj35.

This snippet of code works ok on gcc 11.1, but fails to compile on gcc 11.2 and
trunk (12).

```
typedef struct {
    union {
        struct {
            const void* content;
        } put;
    };
} op_t;

op_t f(const char* alias) {
    return op_t{
        .put =
            {
                .content = alias,
            },
    };
}
```

The error message (compiled with `-std=c++20` but the standard version seems
irrelevant):
```
<source>: In function 'op_t f(const char*)':
<source>:15:5: error: 'op_t::<unnamed union>' has no non-static data member
named 'content'
   15 |     };
      |     ^
Compiler returned: 1
```

>From the error message, it seems that the compiler searches for `content` data
member inside the unnamed union and not in the unnamed `put` struct.
