Invalid core generated with GHC 7.10 RC3
Using the Shake repo (https://github.com/ndmitchell/shake.git) at commit d7fa04 and GHC 7.10 RC3 or GHC HEAD, if I {{cabal test}} I get the error:
## BUILD oracle --quiet *str-int
TESTS FAILED
shake-test: Expected an exception but succeeded
Discussion about this issue can be found on the mailing list: http://osdir.com/ml/general/2015-03/msg25847.html
GHC generates the Core:
case (\_ -> error "here") of {}
This is invalid GHC Core. I intend to track down a minimal example shortly.
