I believe this issue is specific to gcc-4.6.2, not with less than
boost-1.49, and I have what I think is a fix. Here's the error:

You can find a full build log and preprocessed id_manager.cpp at
<https://bugs.gentoo.org/show_bug.cgi?id=411691>. Basically I noticed that
if I changed the optimization level to -O[01s] or if I removed -DNDEBUG
(enabling assertions), it built without error. I came up with both an
arbitrary patch, and one that I think makes sense (but itself could be
arbitrary since I don't fully understand what the problem is):

Usually base classes need a virtual destructor, though not if you know the
actual type of the object when it's destroyed. Anyway, it works now.
