I think you should report this as a bug against openssh source
package and see if you get any assistance. As the segfaults happen
inside libwrap and libc it could end up being a bug in either of
those instead, or in how sshd uses them, but let's see.

Using "reportbug openssh-server" is probably the easiest.

Cheers,
Andy
