Description (last modified by eskimor)

Compiling jsaddle-dom (the JSDOM.Types module in particular) requires quite a lot of memory on 8.2.2 already, but with 8.4.3 I am no longer able to compile it at all with 8 GB of RAM. At first I thought it could be related to #15304 but passing -fno-worker-wrapper does not seem to make much of a difference, therefore it might be a different cause here.


git clone
cd jsaddle-dom
sed -i 's/? "default"/? "ghc843"/1' shell.nix
cabal new-build
