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.
