Bug ID: 103290
Summary: gcc 11 regression with C++ designated initializers,
unions, anonymous struct
Product: gcc
Version: 11.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: roland at gnu dot org
Target Milestone: ---
```
struct S {
union {
struct {
unsigned short x;
} s;
};
};
S foo() {
S x = {.s = {.x = 1}};
return x;
}
```
with g++
produces error: 'S::<unnamed union>' has no non-static data member named 'x'
This is a regression from GCC 10. The same code compiled as C still works.
Reproduced on trunk at 4cdf7db9a39d18bd536d816a5751d4d3cf23808b and on 11
branch at b52e2254b30445f3cd667ae0f0d99b183394e37b.
