Bind 9.5.1b1exiting (due to assertion failure)

[Rob Tanner]

I've just started running 9.5.1b1 compiled from source yesterday 
afternoon and last night it died and here are the last two log entries:

Jul 15 23:12:51 minerva named[15228]: resolver.c:5617: REQUIRE((((query) 
!= ((void *)0)) && (((const isc__magic_t *)(query))->magic == ((('Q') << 
24 | ('!') << 16 | ('!') << 8 | ('!')))))) failed
Jul 15 23:12:51 minerva named[15228]: exiting (due to assertion failure)

Can anyone tell me what might be wrong and what to do to fix it?

Thanks.
