Not only related to threading, but the issue is barely visible in single threaded execution.

The patch includes a bit clean up in project settings + code.

The shared s0 state in a DFA was deleted when setting a new one (from the DFA entries possibly). That could led to a situation where a valid reference was deleted, even though it's still needed.

Additionally fixed some formattings and updated the XCode projects in the demo.
