Bad Access crash - seeking advice/ideas

Hello,

I'm hoping someone who has a little more knowledge of deep-Swift can help me interpret this rather frustrating crash that I'm experiencing. The problem seems to be mixed up with my usage of Combine, which I believe is part of why it is so difficult to hone in on the actual source of the problem. Based on the screenshot below this looks to me like it comes down to some sort of infinite recursion, maybe due to a carelessly wired synchronous publisher or something like that, so my main question is whether that seems correct or if perhaps "buildDemanglingForMetadata" is a clue that someone else can see points in a different direction. Thanks very much!

Thanks for giving me another possible lead. Here's the stack trace before it hits the infinite recursion - does anything in here shed more light on your theory?

@wtedst Do you have any suggestions about how I could go about tracking down the source of the issue? I still haven't fixed it and it's very demoralizing :/
