Panic (something to do with floatExpr?)
Loading
main = let (x :: String) = "hello" in putStrLn x
using a very simple driver for the GHC API (see T145.hs) causes a ghc panic:
[1 of 1] Compiling Main ( T145-input.hs, interpreted )
T145: T145: panic! (the 'impossible' happened)
(GHC version 7.10.0.20150128 for x86_64-apple-darwin):
floatExpr tick

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
This panic is arising in our test case for #8333 (closed), so it may be related to that bug.
