  A void * and an int, or an int *? Generally speaking, one can cast any
type of pointer into a void *, and cast a void * back to any other type of
pointer (without casts! At least in ANSI C; I think in C++ you need a
cast). But if you mean casting a pointer (of any kind) into an int (or
unsigned long, or whatever) then yes, I can see where that would definitely
lead to problems.
