Release Notes:

Hide
The compiler emits an arguably spurious error on an access of a const static data member through a pointer when a constant expression is required. While gcc allows this silently, both the TI compiler and clang emit errors in stricter modes.

struct C { const static int m; };
const int C::m = 4;
C c, *cp = &c;
int main(void)
{
struct S02 {
int x : cp->m; // error, not a constant expression
};
}

Access of const static member through pointer is not a constant expression.
