schedule: re-entered unsafely on minimal hello world program on arm
i installed ghc 7.10.3 from jessie-backports (together with the corresponding LLVM 1:3.5.2.3~bpo8+2) and get for the minimal main = putStrLn "hello" program the error message
testthree: schedule: re-entered unsafely.
Perhaps a 'foreign import unsafe' should be 'safe'?
i am not certain if this is related: cabal install for the same minimal program (with a minimal cabal file) hangs. cabal install -v gives

Redirecting build log to {handle: /home/frank/.cabal/logs/testthree-0.0.6.log}
any comment how this can be fixed? thank you - a running 7.10.3 for armhf is a great achievement!
