scanl is buggy in the CUDA backend

Reported by: chak Owned by: tmcdonell
Priority: major Milestone:
Component: CUDA backend Version: 0.7.1.0
Keywords: Cc:

Description

The scanl function returns an incorrect result for arrays of some size (eg, for 1800 elements on my MBP, GeForce 9600M GT). The prescan array appears to be correct, but the scalar component of the result appears entirely unrelated to the correct result.
