Here buffer will only meet the alignment requirements of char. IIUC, 
char[buffer_size] generates properly aligned storage for something of 
size buffer_size only when used in a new expression:

    char * buffer = new char[buffer_size];

Anyway, perhaps you could into boost::aligned_storage for your purposes.
