Re: [Haskell-cafe] Difficult memory leak in array processing

I have the following code whose purpose is to add dither (noise) to a given array. The code looks very straightforward but apparently it has a memory leak somewhere. Here I try to run the algorithm for an array of 10,000,000 integers. Ten million unboxed strict integers should equal to 40MB which should pose no problems to any modern system. However, the program fails with a stack overflow error. I'm using GHC 6.6 on Windows with 1 GB of RAM.

I'm also unable to reproduce this. Can you tell us exactly what commandline you are using to compile and run the program please? Thanks Ian
