--- Comment #1 from TC <rs2740 at gmail dot com> ---
The full-expression of the initialization of c0 includes the lvalue-to-rvalue
conversion on someVar[0], which is not allowed in a core constant expression;
see [expr.const]/2.7. Note that [expr.const]/2.7.1 only applies to complete
objects, which someVar[0] is not (it's a subobject).
