9.4 branch build failure on ByteString/Internal.hs
i've found for the last couple of weeks, the 9.4 branch fails to build with the following error. is this known? a fix in the works? ``` libraries/bytestring/Data/ByteString/Internal.hs:292:23: error: • Couldn't match type ‘m’ with ‘TH.Q’ ‘m’ is a rigid type variable bound by the type signature for: TH.lift :: forall (m :: * -> *). TH.Quote m => ByteString -> m TH.Exp at libraries/bytestring/Data/ByteString/Internal.hs:292:3-6 Expected type: m TH.Exp Actual type: TH.Q TH.Exp • In the expression: [| unsafePackLenLiteral |] `TH.appE` TH.litE (TH.integerL (fromIntegral len)) `TH.appE` TH.litE (TH.BytesPrimL $ TH.Bytes ptr 0 (fromIntegral len)) In an equation for ‘TH.lift’: TH.lift (BS ptr len) = [| unsafePackLenLiteral |] `TH.appE` TH.litE (TH.integerL (fromIntegral len)) `TH.appE` TH.litE (TH.BytesPrimL $ TH.Bytes ptr 0 (fromIntegral len)) In the instance declaration for ‘TH.Lift ByteString’ • Relevant bindings include lift :: ByteString -> m TH.Exp (bound at libraries/bytestring/Data/ByteString/Internal.hs:292:3) | 292 | lift (BS ptr len) = [| unsafePackLenLiteral |] | ^^^^^^^^^^^^^^^^^^^^^^^^^^... ``` -- Shayne Fletcher
never mind. i see that's it's been discussed and there's a ticket https://gitlab.haskell.org/ghc/ghc/-/issues/21633 and a related MR https://gitlab.haskell.org/ghc/ghc/-/merge_requests/8332. On Tue, May 24, 2022 at 5:34 PM Shayne Fletcher < shayne.fletcher.50@gmail.com> wrote:
