I installed a Bhyve VM with CURRENT (latest as of today - r361307) and proceeded to get the ports tree and install tmux. It has a dependency on Perl, which fails to build thus : cc -pthread -Wl,-E -fstack-protector-strong -L/usr/local/lib -o miniperl mpdtrace/opmini.o mpdtrace/perlmini.o mpdtrace/gv.o mpdtrace/toke.o mpdtrace/perly.o mpdtrace/pad.o mpdtrace/regcomp.o mpdtrace/dump.o mpdtrace/util.o mpdtrace/mg.o mpdtrace/reentr.o mpdtrace/mro_core.o mpdtrace/keywords.o mpdtrace/hv.o mpdtrace/av.o mpdtrace/run.o mpdtrace/pp_hot.o mpdtrace/sv.o mpdtrace/pp.o mpdtrace/scope.o mpdtrace/pp_ctl.o mpdtrace/pp_sys.o mpdtrace/doop.o mpdtrace/doio.o mpdtrace/regexec.o mpdtrace/utf8.o mpdtrace/taint.o mpdtrace/deb.o mpdtrace/universal.o mpdtrace/globals.o mpdtrace/perlio.o mpdtrace/perlapi.o mpdtrace/numeric.o mpdtrace/mathoms.o mpdtrace/locale.o mpdtrace/pp_pack.o mpdtrace/pp_sort.o mpdtrace/caretx.o mpdtrace/dquote.o mpdtrace/time64.o mpdtrace/miniperlmain.o dtrace_mini.o -lpthread -lm -lcrypt -lutil LD_LIBRARY_PATH=/usr/ports/lang/perl5.30/work/perl-5.30.2 ./miniperl -w -Ilib -Idist/Exporter/lib -MExporter -e '<?>' || sh -c 'echo >&2 Failed to build miniperl.

Builds fine on FreeBSD 13.0-CURRENT #0 r361421 (amd64) with debugging disabled for world and kernel in Hyper-V.
upgraded to r361429, problem went away
