QQUIX: The crash occurs: (1) if the NPC has no spells, (2) has a few spells or (3) has a leveled spell list.

Memory for the Future: sizeof(array) doesn't get the number of element in the array.
use sizeof(array)/sizeof(element_type);

QQUix assumptions were actually wrong. The crash was caused by trying to access an invalid segment of memory, possibly superating a page boundary, becouse there were excessive iterations
