    Dear maintainers,

    Compiling the haskell-clash-ghc failed for loong64 in the Debian Package Auto-Building environment.
    The error log is as follows,

    I thought we fixed those errors with GHC 9.6.6-4, where we applied the
    patches from https://bugs.debian.org/1089921. What are we missing?

    Please consider the patch I attached.

    Can we stop patching every Haskell package to pass the --ghc-options="-optc-mcmodel=medium" flag? The plan was to remove this work-around now that we have the proper fix in GHC.

    Thanks,
