Assertion failed: (!v), function Eval, file Trigger.cc

[leres]

We're running a standalone bro/broctl config (1.5.3) to watch a 10G link that has IPv4 and IPv6 traffic on it and have seen several crashes over the last week. I recompiled with -g so there are symbols for the stack trace.

I think it's probably a coincidence that the "lookup_addr() only supports IPv4 addresses" error appears right before the assert() failure so I opened a new ticket.

Without looking more closely yet, my guess is it's still related to
IPv6 in some form, perhaps the trigger setup doesn't handle the error
cases correctly in some cases. Tagging this with "ipv6" and marking
for 1.6 to at least check whether it's something obvious we can fix
quickly.

[seth]

I'm pushing this ticket back to 1.7 so that we can include it in the more broad check over the IPv6 support.
