Aha.  But it sounds like it's not just me who is confused.  Here's
just two examples:

  From doc.c:

      strp = SDATA (string);
      while (strp < SDATA (string) + SBYTES (string))

  (why not "while *strp"?)

  From fileio.c:

      nm = (unsigned char *) alloca (SBYTES (filename) + 1);
      bcopy (SDATA (filename), nm, SBYTES (filename) + 1);

  (why +1? it potentially accesses memory beyond end of `filename's
  contents)

Anyway, thanks.  I will fix the code I committed.
