--- Comment #3 from Ed Maste <emaste at freebsd.org> ---
Create a directory and uncompress pty.ko.gz there. Then

% cd <dir>
% kldxref -v .
volta% kldxref -v .  
./lhint.YF8PCY
kldxref: elf_open(./lhint.YF8PCY): Inappropriate file type or format
./pty.ko
kldxref: ef_seg_read_rel(./pty.ko): bad offset/len (552:33)
kldxref: error while reading ./pty.ko: Bad address

The "bad offset/len" is the issue described here.
