It was thus said that the Great Brian Hechinger once stated:
IMHO that's *always* a good thing. it has really opened my eyes to the fact
that your average opensource coder has been so coddled by the whole gcc/x86
platform that they have really started to make stupid mistakes and even
stupider assumptions about things. the most common assumption is that a
void pointer and an int pointer is the same size. which just happens to be
true in 32-bit land, but totally hoses those of us who live in 64-bit land.
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.

in the Standard C library of that system that I triggered ... )
