Hi Henk-Jan,

I believe cabal adds a -O on the command line, perhaps try ghc --make -O (after deleting all object files)

If it’s the -O option what causes the loop then it is problably because of this:

It is the -O option. How do I get/install the patch mentioned in this ticket?

My workaround is to change the source which is compiled. Instead of the method implementation id = arr id, I use the implementation id = arr Prelude.id. Best wishes, Wolfgang
