It appears that you dropped into a debugger after the trap. This seems to be an OS issue, and I would suggest using the OpenBSD supported forums. i.e. IRC #openbsd or #openbsdhelp, the website: http://www.openbsd.org, or the mailing lists(you can get them off the website).

Make sure that you search to see if others have had this previously, and if there is a patch available.

Good luck!
