Re: [Boost-users] [Boost.Asio] Segmentation fault when ::getaddrinfo() returns EAI_SYSTEM without system error code set (errno = 0) - is this a bug?

In proposed status_code we supply a getaddrinfo_code, so getaddrinfo codes get their own status code domain. EAI_SYSTEM compares equal to errc::resource_unavailable_try_again:

Not sure how I feel about that. I also have just noticed that while POSIX says "[EAI_SYSTEM] A system error occurred; the error code can be found in errno.", which IMHO clearly says errno must be != 0, https://man7.org/linux/man-pages/man3/getaddrinfo.3.html says "EAI_SYSTEM Other system error, check errno for details.". I guess the later could accept errno == 0, meaning "no details".
