ASN1C v6.7 Beta is out, with new features for users of C++11. Instead of generating code with the -cpp option, use -cpp11, and ASN1C will generate code using C++ Standard Library classes std::array, std::list, and std::string, in place of normal C++ static arrays, Objective System's doubly-linked list classes, and plain char* fields, respectively.  Using configuration files, you can also make use of std::vector or std::deque.  Give it a try!
