--- Comment #6 from Ed Maste <emaste@freebsd.org> ---
Using QEMU's `-d exec` option I see last instructions before the exception =
are
in these regions:

Chain 0: 0x18a5f40 [0000000000000000/ffffffff8105176a/0x40c2b0] ^M
Chain 0: 0x18a60c0 [0000000000000000/ffffffff80c40a50/0x40c2b0] ^M
Chain 0: 0x18ae840 [0000000000000000/ffffffff8104dd60/0x40c2b0] ^M
Chain 0: 0x18a6900 [0000000000000000/ffffffff80c40a84/0x40c2b0] ^M
Chain 0: 0x18a6bc0 [0000000000000000/ffffffff81051779/0x40c2b0] ^M
Chain 0: 0x18a74c0 [0000000000000000/ffffffff80c4058a/0x40c2b0] ^M

Symbols associated with these addrs:

ffffffff80c403f0 T link_elf_ireloc
ffffffff80c40a50 t elf_lookup_ifunc
ffffffff810516e0 t elf_reloc_internal
ffffffff8104dd60 t copyout_resolver

the last instructions executed are in link_elf_ireloc()
