#3903: DPH bad sliceP causes RTS panic "allocGroup: requested zero blocks"
--------------------------------------+-------------------------------------
Reporter: benl | Owner: benl
Type: bug | Status: new
Priority: high | Milestone: 6.14.1
Component: Data Parallel Haskell | Version: 6.13

Os: Unknown/Multiple | Blocking:
Architecture: Unknown/Multiple | Failure: Compile-time crash

Comment(by benl):
So DPH doesn't do array bounds checks because they interfere with
optimisations. I think in the long term we'll want to provide a Safe API
as well as an Unsafe one. The idea being that the programmer develops and
tests their program with the Safe API, before switching to the Unsafe (and
faster) one.
