This is a bug. It works if the variable doesn't have a known value!
It also works in optimize(WANTinterpret) but not CTFE,

----
static const int glob10251 = 7;

const (int) * bug10251()
{
   return &glob10251;
}

static a10251 = &glob10251; //  OK
static b10251 = bug10251(); // Fails

Fix bug 10251 CTFE: Allow returning pointers to global statics of known value

Don't expand pointers to global variables.
They should stay as a SymOffExp, even if their value is known.
