SYMPTOMS
When you compile a template class that contains a data member that is an array of a second template class, and the second class contains a data member that is an array, and the size of both arrays is dependent on a template parameter, you may receive the following error:
error C2233: '<Unknown>' : arrays of objects containing zero-size arrays are illegal
RESOLUTION
Use a pointer instead of an array. Allocate the space for the array in the constructor, and deallocate the space for the array in the destructor.
