It looks like some kind of message from your C++ compiler's runtime
library.

One possibility is that your compiler has C++'s RTTI feature disabled by
default (e.g. MSVC) and you're not using Boost.Build to build all your
code like the Boost.Python instructions suggest.  I can't think of any
other explanations right now.
