Okay, and then I also said:

I'm happy to help you look at this, but you'll need to provide a way
to reproduce the issue.
I actually did make some progress... Pivy currently passes -includeall to swig, and from my googling that's generally a bad idea so I'm applying a patch to remove it.
I still don't know much about swig but my understanding is that keeps it from trying to process all the headers and instead just the ones in the swig template.
Now the error is narrowed down to:
But it's erroring on the second 2nd binding (and there's many more)

Next I'm going to patch it to run swig with debugging so I can get more details... My guess is there was an incompatible change between Coin3 and Coin4 but I'm running the latest checkout of Pivy and it's all the same upstream. If that's the case then they messed up.
Thanks,
Richard
