--- Comment #1 from hstong at ca.ibm.com ---
someVar[0] is not a core constant expression.

It applies lvalue-to-rvalue conversion to a glvalue referring to a subobject,
_of_ but not _being_ a complete non-volatile const object with a preceding
initialization.

See WG 21 document N 4687 subclause 8.20 [expr.const] bullet 2.7.
