Brace initializers break find usages on auto variables

In the following code block

struct TestStruct
{
    int test;
};

void TestFn()
{
    TestStruct a = TestStruct{};
    auto b = a;
    int x = b.test;
    auto c = TestStruct{1};
    x = c.test;
    auto d = TestStruct();
    x = d.test;
}

Find usages only finds usages of test from b and d. c is not found. This is a little strange as the refactor tool still gets it.

This is a problem with the clang code model and the regular code model.
