Yeah, I get this one too. I thought commit 37d5babb5cfa ("jit: Support
opaque pointers in LLVM 16.") was going to silence it, but I was quite
mistaken. I gave that code a quick look and could not understand what
it was complaining about. Is it a bug in the LLVM headers?
Adding Andres and Thomas to CC, because they're the ones touching the
LLVM / JIT code.
Any clues?
