Question about malloc_useable_size

Hi,

this is about Bug #962 and Ulis changes in nis-netgrp.c:

nis-netgrp.c contains the following code:

      assert (len > 0);
      assert (malloc_usable_size (netgrp->data) >= len + 1);
      assert (netgrp->data[len] == '\0');


netgrp->data was created with malloc (len + 1); But there is a
report (see Bug #962), that the assert sometimes fails with
malloc_usable_size (netgrp->data) reporting 992, while len is 1002.
How can this happen?

 Thanks,
   Thorsten
