Thanks! The problem was that when we moved to Catch2 from GoogleTest, it was injecting printouts of the values in the Catch2 macros, and by default there's no ostream operator for these. Manually splitting the bool checks into two lines fixed it. We used to have Boost tests, but they were lost some time ago with GHA/Azure dropped Boost by default. I've readded a simple Boost job.
