Unbound crash with fatal error - error_supers: assertion 0 failed

Sat Jul 7 19:16:47 UTC 2018

Running Windows 10/65 v1803 b17134.137

I have included salient bits from the log which starts as you can see at
12:38 and all is working just fine until 17:17 apart from the bits I have
included below. There are quite a few: 

"event_add failed. in cpsl." (more than I have included)
