If someone has any other idea before then, I'm all ears. It did not seem to fix the issue. I tried using a patch like the attached, but the "check" package still seems to fail its test suite in the same way as before. Something else must be going on. Maybe the best thing to do is to try to manually create a minimal reproducible case, and then investigate using that simpler case. -- Chris
