Unregisterised compiler: arithmetic failure
Compiling the following with RC2 on powerpc 64 downloaded from haskell.org:
main = putStr $ show (-1.0000000001 :: Double)Setting -O yields:
0.0Without optimization the correct result is displayed.
I prepared an unregisterised compiler on amd64 and see the same issue and more arithmetic tests fail in testsuite. In fact I took the above from arith005.
