Friends I'm working on !15719, which is a big step towards making `base` reinstallable. But in one build I'm getting a strange failure, below, just in one build x86_64-linux-fedora43-release https://gitlab.haskell.org/ghc/ghc/-/jobs/2484333 Now, it's likely that this failure is due to my patch. *But I can't reproduce it locally*. How can I repo? I tried hadrian/build --flavour=release but that didn't fall over. Thanks!
