Hi Joaquin,
I've been working on a boost::flyweights::intermodule_holder_class-like intermodule_singleton class. It's in early design state. This class is doing some lazy variable and shared memory initialization, so maybe it can be useful to implement intermodule_holder. It's in trunk, in boost/interprocess/detail/intermodule_singleton.hpp. It's not optimized for windows (it uses file locks and kernel lifetime shared memory, emulating a unix process, it would be much more lightweight using native windows process-lifetime resources) but I think you should try it. I've not tested in DLL-s.
You have a test (intermodule_singleton.cpp) in boost/interprocess/test that shows some use cases.
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:
