well, as I understood this the __bss_end being a char[] did implicitly
take the address when accessing __bss_end (as we do when we have a
definition of char foo[2] and we take just 'foo'). But you say here we
should reference the address of __bss_end while it was still of type
char[]. Sorry, I do not understand that, can you please clarify?
