libunwind may or may not be broken on mips, so i'm not sure where the point blame here. Should an unwind be caused at all by trust-dns? I'm unsure if this is an assert or unwrap somewhere.

It looks like backtrack may be having issues there? Backtrace is optional on master. Perhaps you can try the master branch? Though that has a lot of new tokio implementations, so it may not be easy.

Yes libunwind isn't that great. I'll try master later, thanks!
