That's Linux's BPF interpreter, but the same problem exists with the *BSD BPF interpreter:
http://www.openbsd.org/cgi-bin/cvsweb/src/sys/net/bpf_filter.c.diff?r1=1.21;r2=1.22http://www.openbsd.org/cgi-bin/cvsweb/src/sys/net/bpf_filter.c?rev=1.22;content-type=text%2Fx-cvsweb-markupDan's program doesn't directly map to *BSD, but something could probably be cooked up.
OpenBSD's fix clears it up.
