The double stars are "pointers to pointers". Very useful when you have a
list of strings (char *'s).
I think if the line was:
xmemmove (*(wclass->superClasses, *(superClass->superClasses), size);
would fix the problem.

P.S. I am assuming that "xmemmove" has the same prototype as memmove
(void *, void *, size_t)
