*main.c:

*main.c:
	Do not repeat random number generator initializations, as memory
	is allocated and never reclaimed.  Also fixed the V4 random number
	generator initialization (a DES_CBC_CRC random number is generated
	and used as a seed for the V4 routine, but the generation function
	was being called with the wrong arguments).

* do_as_req.c:
	Memory was occassionally being freed twice because the pointer was
	not re-initialized to NULL after it was freed.
