Hi Ion,

I've tried replacing my intermodule_holder code with a simple wrapper
around boost::interprocess:detail::intermodule_singleton
and unfortunately the problem persists, hitting at the very same
line of code with IWbemLocator::ConnectServer. Setting LazyInit to
either true or false does nor make a difference. Call stack
follows:
