Should not explicitly initialize these pointers to nullptr in gcc-4.4 case because nullptr assignment actually requires the calling of a constructor. As a result, the order in which these nullptr initializations take place is not defined with respect to other initializations. A pointer that is left without explicit initialization automatically gets nullptr anyway, so just don't explicitly initialize these.
