Describe the bug

• OS and Version: Mac OS Catalina
• VS Code Version: 1.37.1
• C/C++ Extension Version: 0.25.1

To Reproduce

struct foo { 
    int some_field;
};

void bar() { 
    struct foo x = {
        .some_field = 1
    };
    x.some_field = 2;
}

1. Invoke "Find All References" on some_field in line 2
2. It will find the assignment (line 9), but not the initializer (line 7)

Expected behavior Find references should have found both references to some_field

It should also be able to find

struct foo x = {1};
