Sorry, I don't see the bug.  For example, here's the malloc function
that you mention:

   char *
   rpl_malloc (size_t n)
   {
     if (n == 0)
       n = 1;
     return malloc (n);
   }

If the underlying malloc returns a suitably-aligned block, then
rpl_malloc will do so too.

Also, GNU tar doesn't invoke getdents, so I don't see why that's
relevant.
