If anybody is interested I can create a small solution with a project file to reproduce it.
Looks like
boost::random_access_traversal_tag
doesn't have a "best conversion" among
std::input_iterator_tag
std::random_access_iterator_tag
My guess is this is where that proxy reference bites you, as it makes your Enumerator iterator not strictly a random access iterator, even though it morally is, so boost::iterator_facade won't set your iterator_category to std::random_access_iterator_tag and instead tries to go a middle-of-the-road approach (IIRC). Try typedef'ing
typedef std::random_access_iterator_tag iterator_category; // I think this is right...
in your Enumerator definition and see if MSVC complains?
