----------------------------------------------------------------------

In perl-5.26.2/Configure there is following test.

----------------------------------------------------------------------
        if $test -f $dtrace
        then
                if $dtrace -h -s ../perldtrace.d \
                        -o perldtrace.tmp >/dev/null 2>&1 \
                        && rm -f perldtrace.tmp
                then
                        echo " "
                        echo "Good: your $dtrace knows about the -h flag."=
=20=20=20=20=20=20
                else
                        cat >&2 <<EOM

*** $me:  Fatal Error:  $dtrace doesn't support -h flag

*** Your installed dtrace doesn't support the -h switch to compile a D=20=

EOM
                        exit 1
                fi
                break;
        fi
----------------------------------------------------------------------

And when I executed this test on command line, it result in following error.

----------------------------------------------------------------------

----------------------------------------------------------------------

But on 12.0-BETA1 it succeeds without any error.

----------------------------------------------------------------------
yasu@rolling-vm-freebsd3[2006]% uname -a
FreeBSD rolling-vm-freebsd3.home.utahime.org 12.0-BETA1 FreeBSD 12.0-BETA1

yasu@rolling-vm-freebsd3[2008]% dtrace -h -s perldtrace.d -o perldtrace.tmp
yasu@rolling-vm-freebsd3[2009]%
----------------------------------------------------------------------

So there is regression about dtrace between base r339436 and base r339548.
