Description
(Tried to select "bug" template but it wouldn't let me select any.)
I just installed ghc8.10.5 (via ghcup) on macOS Big Sur (11.4).
I did a "cabal update" (cabal 3.4) and then started rebuilding a library, noticed it hanging. Re-ran "cabal build" with "-v -j1" and got a lot of output, ending with:
```
creating dist/build
creating dist/build/autogen
creating dist/build/autogen
Preprocessing library for nonlinear-optimization-0.3.12.1..
creating dist/build/Numeric/Optimization/Algorithms
creating dist/build/Numeric/Optimization
creating dist/build/Numeric
creating dist/build/Numeric/Optimization
creating dist/build/Numeric/Optimization/Algorithms
/Users/adam/.ghcup/bin/hsc2hs '@dist/build/Numeric/Optimization/Algorithms/hsc2hs-response54797-14.txt'
```
Where it simply hangs. hsc2hs is running but not using significant CPU or memory.
Hand-installing hsc2hs 0.68.8 from github and replacing the ghcup links so it uses that one seems to solve the problem.
Reported this at the ghc gitlab and @bgamari suggested reporting here.
