There is a bug in QEMU cpu emulation. It interpretes some SSE instruction in the pfctl binary incorrectly. If I remeber correctly this happnes in set_ipmask(). ipsecctl has the same issue. When compiling pfctl with -O0, clang does not put these instructions into the binary. Currently I cannot reproduce it with qemu-4.1.0 from ports. I have not tried it for a long time. It seems that I ran into this isssue in 2018. Which version of qemu do you use? bluhm
