Release Notes:

Hide
The following code results in a syntax error, while it is accepted by both gcc and clang.

int main()
{
    char c = 1;
    const int &&r = static_cast<const int&&>(c);
    return r;
}

As a workaround, 'c' may be cast to int. However, doing so will not bind reference r to the variable c.
