Probable cause is std::vectorstd::function initialized by default in GGE::Entity
NB same issue if [this] capture is removed in lambda (std::vector::value_type) as default initialization
Fixed : Default constructor call that assign std::map with a mapped_type like std::function using an initializer_list created a garbage map.
Result is a call to an std::null_ptr.
