I just updated to OpenBSD 7.8 along with the packages I use, and rspamd(8)
won't start. I pkg_deleted it and its dependencies along with all the
associated directories before re-installing rspamd-3.14.0. After
installation, rspamd -v crashes with "Illegal instruction (core dumped)". I
think this may be related to IBT on my machine. When I install rspamd on a
VPS running OpenBSD 7.8, rspamd -v does not crash. Is this related to
https://marc.info/?l=openbsd-ports&m=176008480027301&w=2? If so, can a fix
be pushed to -stable? I use rspamd(8) for spam-filtering but more
importantly DKIM, so this package is more important to me than some others.
