You can run gdb on it:

$ gdb /path/to/ruby /path/to/core

Then type "bt" to get a backtrace and you can learn other commands.

I suspect this is a bug somewhere in FreeBSD 9.0 BETA3 itself, and
not Unicorn or Ruby.

Can you test some simple scripts using trap?

Something along the lines of:
---------------------- 8< ---------------------
trap(:HUP) do
  puts "HUP received"
end
puts "#$$ ready to receive SIGHUP"
sleep
------------------------------------------------

Thanks.
