When running the Vim tests with UBSan, the following errors are

Line 713 is is this for me:
713 memcpy((char *)&server.sin_addr, host->h_addr, host->h_length);
I don't see this error with ubsan. A char* should not require 8 byte
alignment anyway. Strange.
This is a strange one. I would guess at a compiler issue. Stack
overflow coughs up these somewhat related issues on OSX which I think
you are using:

h_addr is usually a macro to h_addr_list[0] where h_addr_list is a
char**. If you aren't seeing a problem it may be a false positive.
