This proof of concept drafts a possible workaround by relying on `hickory-dns` [2], using the hickory-resolver for name resolution instead of the default `getaddrinfo` based `GaiResolver` used by the hyper http client, as suggested by Thomas. These patches still need some polishing, but allow already to compile a static binary without the glibc issues as descibied in the issue, therefore sending them for possible more widespread testing. Initial testing on ArchLinux with glic 2.40+r16+gaa533d58ff-2, previously leading to floating point exceptions, now allows to backup without issues using the patched client. A major downside is the required dependencies for hickory-dns`, as with the feature `system-config` enabled (used to read nameservers from `/etc/resolv.conf`), also the windows dependencies on `ipconfig` and it's subdependencies are required.
