DPH bad sliceP causes RTS panic "allocGroup: requested zero blocks"
$ ghci -XPArr
...
Prelude> :m GHC.PArr
Prelude GHC.PArr> sliceP 10 10 [::]
<interactive>: internal error: allocGroup: requested zero blocks
(GHC version 6.12.1 for i386_apple_darwin)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Abort trap
sliceP 10 10 [::]
is bogus. This should have been picked up in the libraries before hitting the RTS assertion.
