this seems more likely to be a problem with your boost (I've played
around with various gr-howto versions very recently and did never see this).
Which Boost version do you have?

Yes, seems like a problem with Boost, but it's strange that it doesn't happen when just building GNU Radio.
Achilleas, when you say you're using the latest trunk, are you talking about the master or next branch? I'm assuming the next branch since the master branch's "gr-howto-write-a-block" is autotools only and a separate "gr-howto-write-a-block-cmake" exists for the cmake build.
Also, what OS?
