That's precisely what I'd like to ask you :) Could you trap the assertion
and dump the stack trace? Hopefully, that'll reveal the type of the
object which is causing the problem.

As for Boost.MultiIndex, there's no static object involved neither
in the lib nor the tests, AFAIK, but if you could get that stacktrace
we could tell better.
