#define DNDEBUG
As Justin told you earlier, the line above should be: #define NDEBUG to eliminate the overhead of bounds-checking, etc. On the compiler command-line, it is "-DNDEBUG", which is the concatenation of the "-D" option, meaning to define a preprocessor symbol, and "NDEBUG", the literal symbol.
