[Bug libc/808] New: Unclear malloc error detection message

[hjl at lucon dot org]

There are

  oldp    = mem2chunk(oldmem);
  oldsize = chunksize(oldp);

  /* Simple tests for old block integrity.  */
  if (__builtin_expect ((uintptr_t) oldp & MALLOC_ALIGN_MASK, 0))
    {
      errstr = "realloc(): invalid pointer";
    errout:
      malloc_printerr (check_action, errstr, oldmem);
      return NULL;
    }
  if (__builtin_expect (oldp->size <= 2 * SIZE_SZ, 0)
      || __builtin_expect (oldsize >= av->system_mem, 0))
    {
      errstr = "realloc(): invalid size";
      goto errout;
    }

in malloc/malloc.c. "invalid size" is not very clear that which size
is invalid, new or old.

No message will ever explain it in detail.  So don't complain about the change I
made.
