This is just triggering undefined behavior: after the constructor call dim is
bound to a temporary long created on the fly from the double _dim, which
disappears by the time newValue is called. Nothing to do with std::valarray or
whatelse.

Oh, you just want a warning for this. Indeed, ICC spills one with -Wall. Maybe
Manuel has an opinion...
