The problem was that realloc got called on memory that had been
allocated prior to dumping, and the malloc information that was used
then had disappeared.

Can you show the code which called realloc on that memory?  I'm
surprised that Emacs does that, but perhaps I'm missing something.

Here's the code that I stumbled across (as a result of a SEGV). I haven't checked to see if there are other examples. From terminal.c:

/* Deletes the bootstrap terminal device.
   Called through delete_terminal_hook. */

static void
delete_initial_terminal (struct terminal *terminal)
{
  if (terminal != initial_terminal)
    abort ();

  delete_terminal (terminal);
  initial_terminal = NULL;
}
