- Subject: [PATCH] resolve: fix segmentation fault with musl >1.1.20
-
- When compiled with musl >1.1.20, fastd will crash in case it can't
- resolve a peers hostname. This is due to a changed implementation of
- freeaddrinfo in musl 1.1.21 onwards.
-
- This segfault is fixed by not calling freeaddrinfo in case the supplied
- pointer is null.
