  -----------
  Add some null pointer checks to avoid segfaults.
When compiled using gcc 6, the initialization process generates segfaults at
some null pointer dereferences. This problem was probably exposed by the
behaviour of -fdelete-null-pointer-checks in gcc 6.

Original patch by: Dhionel D?az <ddiaz at cenditel.gob.ve>

I added an extra check as well.
