If it also has no unwind.h then no useful backtrace for it.

Hmm, looks to me like it should have compiled, then failed due
to missing -lexecinfo.  Can you confirm you have HAVE_BACKTRACE_SYMBOLS_FD
in your build/config.h?  And configured with --enable-seccomp?

Friday I'll look into adding that lib to waf.  And, of course, the
prototypes in FreeBSD are not the same, so you should have gotten
warnings in ntpd/ntp-sandbox.c, in function catchTrap().
