The -f option isn't supported, but it worked. Output attached.
I spotted this line:60<--59(pid1245)->io_read_request (-1 4095) = 0 "33000 unexpected-error errno 1073741866\n"
and I did some googling on it. 1073741866 appears to more canonically be 0x4000002A which is the GNU Hurd ENOPROTOOPT error number.
So I suspect that there's a socket option that mtr is using that hasn't been implemented in Hurd.
