I am not sure why clang claims that hash_link offset inside ClientInfo
is not zero despite the fact that hash_link is the first ClientInfo
parent, but I suspect that this is because hash_link is a POD while
ClientInfo sometimes has a vtable that a compiler may place at offset
zero of a ClientInfo object, shifting hash_link data members down.
