For the following code snippet, gcc is able to compile without any warnings and errors, however, clang emits compile error code “lvalue_reference_bind_to_unrelated”.
gcc: https://godbolt.org/z/q3fEqKGb6
clang: https://godbolt.org/z/f51Ehd6s1
Code snippet:
```
void
foo (int &x, int &y)
{
int err = 0, i;
int a[y - 2], b[y - 2];
int (&c)[y - 2] = a, (&d)[y - 2] = b;
}
```
Error message from clang:
```
<source>:6:9: error: non-const lvalue reference to type 'int[y - 2]' cannot bind to a value of unrelated type 'int[y - 2]'
int (&c)[y - 2] = a, (&d)[y - 2] = b;
^ ~
<source>:6:26: error: non-const lvalue reference to type 'int[y - 2]' cannot bind to a value of unrelated type 'int[y - 2]'
int (&c)[y - 2] = a, (&d)[y - 2] = b;
^ ~
2 errors generated.
```
The error message seems weird to me since the type it wants to bind is the same type.
