Yes, I've seen this too. It's rather an elusive bug; sometimes it
happens, sometimes it doesn't. Clearly there's some difference that I
haven't understood yet, but it has stopped me from reporting it.
My best bet is that this is compiler related. FWIW, it builds for me
under 7-CURRENT right now.
Can anybody else help track down the problem? In particular, what
does the message mean?
