The representation of a void* is unspecified, and does
not have to be
the same as a char*,
Um...
6.2.5 Types
...
[#26] A pointer to void shall have the same representation
and alignment requirements as a pointer to a character
type.
Any two types other than char could be in separate
address spaces,
Not quite; there are certain pairs of types which are required to be
"the same". Continuing the above quote:
Similarly, pointers to qualified or unqualified
versions of compatible types shall have the same
representation and alignment requirements. All pointers to
structure types shall have the same representation and
alignment requirements as each other. All pointers to union
types shall have the same representation and alignment
requirements as each other. Pointers to other types need
not have the same representation or alignment requirements.
