Flow graph segmentation fault in library files

I'm trying to build a graph processing database as part of my research, one problem I'm facing right now is regarding flow graph.

I have an InputNode class inheriting form input_node that reads entities from the database, successor to it a multifunctional_node<InputResult std::tuple<InputResult>> that pre-process those entities and filters out some entities that should not be processed later.

The code compiles successfully. When debugging, I can see the InputNode instance getting copied and invoked for the first time, but after that I get a segmentation fault in _flow_graph_cache_impl.h file at tbb::flow::interface11::internal::broadcast_cache by function try_put_task at task *new_task = (*i)->try_put_task(t);

Any ideas on what could be the cause of this problem and how to solve it??
