em(4) and multicast

OpenBSD has ported the em(4) driver from FreeBSD.  At least on
OpenBSD, em(4) is partially broken: it fails to receive multicast
ethernet frames.  This effectively breaks both IPv4 and IPv6
multicast, including IPv6 neighbor discovery.

I have one report that says FreeBSD 4.9's em(4) has the same bug.
Can any more people confirm that this breakage exists?  In -CURRENT?
I don't have a FreeBSD box with em(4).
