Description

The FromIterator<T> methods for Vector and Matrix rely on the type parameter N to allocate space in the iterable.

If the passed in N type parameter is larger than the number of items returned by the iterator, it can lead to uninitialized memory being left in the Vector or Matrix type which gets dropped.
