std::bad_array_new_length is the type of the object thrown as exceptions by the novos-expressões to report invalid array lengths if

1) array length is negative

2) total size of the new array would exceed implementation-defined maximum value

3) the number of initializer-clauses exceeds the number of elements to initialize

Only the first array dimension may generate this exception; dimensions other than the first are constant expressions and are checked at compile time.
