Serious bug in GHC 9.4 on basic math on aarch64
Hi, We found a reproducible error with a simple math test (div/mod) on aarch64. (on linux, on macos), so we want to call for attention on this. https://gitlab.haskell.org/ghc/ghc/-/issues/22282 This was originally caught by this issue: https://github.com/haskell-foundation/foundation/issues/571 Thank you!

Thank you for bringing this bug to our attention Ian, we have triaged it as highest priority and will include a fix in the next release in the 9.4 series. Cheers, Matt On Wed, Oct 12, 2022 at 12:46 AM Ian-Woo Kim <ianwookim@gmail.com> wrote:

Thank you all very much for the quick actions. I see that the fix has been made and is under review! - Ian
agreed! This is a nasty one! (the only similar bug i remember in the past is the double/float confusion in 7.6/7.8, but that was a much much harder to trigger bug) On Thu, Oct 13, 2022 at 1:37 PM Ian-Woo Kim <ianwookim@gmail.com> wrote:
