The crash occurs in deps/azure-c-shared-utility/adapters/socketio_berkeley.c at line 301. This is because addr->a_addr is a bad pointer and on my embedded linux device throws a segment fault

I realize this is a rather strange configuration and is very un-typical, but though maybe some additional error checks are needed here.

Our device allows for DNS entries to manually set even with DHCP turned on. if it has no DNS server defined, this occurs.
