Interesting. I tried this with a slightly older LLVM checkout (6f4f0afaa8ae), from 2021-04-20, contrib/ltree tests run without an issue, even if I force everything to be jitted+inlined+optimized. The git hash in the package version indicates the commit is from 2021-05-20. Upgrading my local checkout to see whether I can repro the problem. If I can we at least have a not too large bisection window... Greetings, Andres Freund
