Thanks for telling us about this. The message results from an internal consistency check of the compiled expression tree. If Saxon finds the error, it reports it and fixes it, but it shouldn't happen, and could cause trouble, so we like to know about it.

I'm not seeing the warning message on the current maintenance release. I'll try and run it against 9.7.0.11.

I'm not seeing the warning with 9.7.0.11 either. But I get it with 9.7.0.3. So I think this is a problem that we have fixed. Marking it "rejected". But thanks for reporting it, and feel free to re-open if the problem persists.

Sorry for that. Indeed the classpath still pointed to 9.7.0.5, when I believed that I was testing 9.7.0.11.
