@mitzimorris, this is just a heads up. I’m going to try to come up with minimal examples so we can track it down.
This mostly has to do with inline array definitions that’s passed to other functions. I think between Stan and the C++ typing, we’ve got some edge cases we’re not handling well.
As soon as I have something concrete, I’ll post an issue. What sort of information would help? The full C++ compiler message too?
