Hi Oleg, thanks for the extra information.
I find it very puzzling that I cannot reproduce these build failures on my machine. I have just rebuilt ghc-resourcet with a modified ghc-mtl, which I suspect is the source of the problem, because it pulls in a newer version of ghc-transformers. I’m going to push this to core-updates and master in a moment. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
