Hello, as soon I try to resolve a domain with 8.8.8.8 it crashes:

The command I run: nslookup youtube.com 8.8.8.8 but ping 8.8.8.8 works just fine.

I have config it with tor.

Thanks.

Is your code newest?

JayBitron commented 5 years ago

I use the latest binary file you provided in the releases tab.

FlowerWrong commented 5 years ago

Please compile it by yourself. The releases are outdated.

JayBitron commented 5 years ago

There are many bugs while compiling as I mentioned in #56 that's why I used the binary.

JayBitron commented 5 years ago

Still from the latest it gives me the same error and crashes while using it with tor but there is no problem with shadowsocks, from what I found tor socks doesn't support udp, so there is a problem it here, it should not crash and give some error instead.
