This happens when I build a project with stack that uses HsOpenSSL (does not happen when I do stack build in the HsOpenSSL project).
I am on macOS (Monterey).
The problem is not limited to macOS, though https://github.com/hackage-trustees/hackage-cli/actions/runs/9759798062/job/26937247345:

• Ubuntu: https://github.com/hackage-trustees/hackage-cli/actions/runs/9758418998/job/26932915407?pr=72#step:8:4040
• Windows: https://github.com/hackage-trustees/hackage-cli/actions/runs/9758418998/job/26932917641?pr=72#step:8:3846

Not sure what the reason is that the hack no longer works with GHC 9.10. Maybe a change in the Cabal library?

Unfortunately, I have no time to check it. I will gladly accept a PR with a fix.

[andreasabel]

If you give me commit rights (here and on hackage) I can give it a shot. Probably I will first see to update the CI, to make sure the fix is portable.

This repo is now under haskell-cryptography org, I'm not sure whether I can give commit rights. @Kleidukos, could you give commit rights to HsOpenSSL to @andreasabel ? He helps a lot in keeping things building (maintains CI of https://github.com/haskell/text-icu and in a number of other projects) and works on Agda.

@andreasabel, I added you to the list of HsOpenSSL maintainers:
https://hackage.haskell.org/package/HsOpenSSL/maintainers/

[Kleidukos]

@vshabanov You should now be able to manage the access list, and I'll send an invitation to Andreas too!
