Comment (by anonymous):

 offset_ptr uses its template parameter {{{OffsetType}}} for its internal
 representation. That means it depends on you how large it is. Per default,
 {{{OffsetType=size_t}}}, which is 4 bytes for 32 bit programs. In
 32/64-bit mixed applications, you should indeed take an 8-byte offset_ptr,
 for example:
 {{{offset_ptr<void, int, unsigned long long> }}}
