The 'real fun' (tm) starts when the bit pattern for the NULL
pointer isn't 'all zeros'.
Using memset() is then broken - I suspect the compiler is
expected to initialise pointers to the correct NULL pattern.
Not that I think anyone sane would consider trying to compile
any 'normal' C code for such a system.
OTOH it is probably why clang is bleating about (int)((char *)0 + 4)
being undefined behaviour.
