I suspect that when splitting the two we put the type-class one back to 20. I'll increase it to 100.

I think the problem arises due to '''arithmoi''' being alone package built with ghc -fllvm. It should not break, but llvm is a bit experimental target (maybe upgrading '''llvm''' version will help, dunno). To workaround it you can buiild arithmoi w/o llvm flag: {{{ cabal install cyclotomic arithmoi -f-llvm --reinstall }}} The steps to reproduce: {{{ # get saucy mkdir saucy debootstrap saucy saucy/ https://mirrors.kernel.org/ubuntu/ chroot saucy/ echo 'deb http://archive.ubuntu.com/ubuntu saucy main universe' > /etc/apt/sources.list apt-get update apt-get install ghc cabal-install ncurses-dev build-essential llvm # unpack ghc, ./configure && make # get latest cabal cabal update cabal install cabal-install # get arithmoi ~/.cabal/bin/cabal install --with-compiler=$(pwd)/inplace/bin/ghc- stage2 cyclotomic # reproduce root@sf:~/ghc-7.8.3# inplace/bin/ghc-stage2 -e 'Data.Complex.Cyclotomic.goldenRatio' <interactive>: internal error: ARR_WORDS object entered!
