due to the presence of intrusive_ptr.hpp. it seems like SFINAE should have kicked in.
Any help with how to work this around? Do we need to fix above header?
I'm not sure why that is, static_pointer_cast is an overload without any SFINAE involvement that should still match to shared_ptr, but the workaround is simple: remove the unnecessary "void" template argument in get_concrete.
