ghc: panic!
Tried to compile some code provided in the course I'm taking and caused ghc to panic. Got this in my command prompt:
` [1 of 1] Compiling Main ( temp.hs, temp.o ) ghc: panic! (the 'impossible' happened) (GHC version 8.0.2 for x86_64-unknown-mingw32): initTc: unsolved constraints WC {wc_insol = [W] throw_a2dw :: t_a2dv[tau:1] (CHoleCan: throw) [W] throw_a2eY :: t_a2eX[tau:1] (CHoleCan: throw) [W] throw_a2fc :: t_a2fb[tau:1] (CHoleCan: throw)}
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug `
