No, it's quite well-defined: "Converting a prvalue of type “pointer to
T1” to the type “pointer to T2” [...] and back to its original type
yields the original pointer value." The fact that the C++03 spec
doesn't make it clear that void* is allowed as T1 or T2 in this
context is in fact an error and the C++11 spec corrects this (see
defect 1120) -- and this is how every C++ compiler in common use does
it. So reinterpret_cast'ing to void* and back is guaranteed safe.
