It may well be compiler specific. The build environment I got this in
is VC9 (Visual Studio 2008). It quite a lerge project and there is
also extensive use of plenty other boost libraries such as asio,
spirit, phoenix and ublas. At this point I cannot completely rule out
some sort of namespace or template lookup issue, even though I usually
take much care to avoid these. From a distance, it sounds like it may
be something like that.

Problem is, this is a customer's project and I don't have access to
either build environment or code right now as it is finished now. All
I can say is that I did pretty much the same as you in your sample and
it only worked when I did like the second part of your example. The
first part threw this assertion. In any case, as soon as I have access
to this project again I will give it another shot and send you the
complete output.

At home here (Linux, gcc-4.6, boost 1.49) I don't get the assertion
and the code compiles fine.

Thanks a bunch!
I will post here once I have the information.

Cheers,
