[Accepted as a DR at the November, 2023 meeting.]

Subclause 7.6.2.2 [expr.unary.op] paragraph 1 specifies:

The unary * operator performs indirection. Its operand shall be a prvalue of type “pointer to T”, where T is an object or function type. The operator yields an lvalue of type T denoting the object or function to which the operand points.

It is unclear what happens if the operand does not point to an object or function.
