Pulseaudio segfaults when ORC is used on x32

I am using a x32 environment on a Gentoo machine with:
- kernel 4.8.14
- Pulseaudio 9.0
- orc 0.4.26
When I enable ORC, start pulseaudio (either 8.0 or 9.0) and use pavucontrol to change the volume of my HDMI sink, pavucontrol and alsa-sink-HDMI segfault.
traps: alsa-sink-HDMI  general protection ip:f77420c0 sp:f3016868 error:0 in orcexec.kq0Hm1
If I change the volume of a analog sink the issues is not triggered. If I change the volume via pacmd or change the volume via mplayer, the issue is not triggered.
When I use "PULSE_NO_SIMD=1 pulseaudio", the issue does not occur as well.
