You can allocate space for a larger array, but you must do at at runtime,
using malloc() or other allocation functions. The total static variable
space cannot exceed 32K. This is a Mac limitation, not one of LSC.

If the node was allocated statically, the fields should be set to zero. If
it was allocated on the stack, or through a call such as malloc(), it will
contain garbage. Try calloc(), or set the field yourself.
