problem with instantiation of templated method, probably detection problem

[eugenca]

Actual Behavior

Problem with FManager::PropertyHolder::emplace_back This is templated method used to emplace arbitrary items in implementation`s vector As I see how library does, it is not instantiating things to type_list, mappings, etc - connected with lambda in emplace_back and user types AddToGlobal1_Property, AddToGlobal2_Property. When it compiles, clang hangs on segmentations, GCC works well (UB??)
