Bug ID: 47693
Summary: C++20 Designated Initializers - Multiple
initializations of same struct member
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++2a
Assignee: unassignedclangb...@nondot.org
Reporter: c...@synopsys.com

Hi,
I believe Clang shouldn't compile the code below with -std=c++20.
struct X
{
int a;
};
int main()
{
X x{.a = 0, .a = 1};
return 0;
}
GCC fails to compile it with the error:
error: '.a' designator used multiple times in the same initializer list
14 | X x{.a = 0, .a = 1};
Clang trunk successfully compiles the example.
