I just noticed that the CONFIGURE_ARGS in x11/pixman should disable
sse2 on AMD64, but this is not working:

> #0 =A00x000000080107c255 in pixman_blt_sse2 (src_bits=3D0x81344f000,
> dst_bits=3D0x804000000, src_stride=3D2400,
> =A0 =A0dst_stride=3D4096, src_bpp=3D32, dst_bpp=3D32, src_x=3D576, src_y=
=3D576,
> dst_x=3D3, dst_y=3D3, width=3D10, height=3D9)
> =A0 =A0at pixman-sse2.c:5330

I rebuilt and reinstalled the pixman with

# cd /usr/ports/x11/pixman
# make BATCH=3Dyes CONFIGURE_ARGS=3D'--disable-vmx --disable-arm-simd
--disable-mmx --disable-sse2' FORCE_PKG_REGISTER=3Dyes install

This did not solve the problem, just gave me a different kind of crash:
