Ah, I see. I still don't understand what went wrong in this particular case,
but at least it makes sense that there's a difference between `-package-db`
and `cabal exec`.
can you please test if `cabal-cargs` behaves in the same way as `cabal exec`
if you add a `-no-user-package-db` or/and replace `-packabe-db` by `-user-package-db`.
Yes! `-no-user-package-db` does the trick.
I have to admit I had forgotten completely about the user DB. When running `cabal sandbox hc-pkg list` I only see the global one and the one in the sandbox. But `ghc-pkg` shows the user DB and indeed it contains `hashable-1.2.6.1` which was causing me trouble.
Cool, problem solved.
Would it make sense then for `cabal-cargs` to always emit `-no-user-package-db` when it discovers a sandbox?
Cheers
