## Summary The c code generated when using capi does not cast a const pointer to a normal pointer. When compiled, the following error is raised: `return discards ‘const’ qualifier from pointer target type` In my test, the code still runs, but as far as I know in c there isn't an implicit conversion from const-qualified pointer types to non-const-qualified ones. So does ghc falls back to ccall? ## Environment * GHC version used: 9.2.2 * Operating System: Archlinux 5.18.16-arch1-1 * System Architecture: x86_64
