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.

No, it doesn't. It can't, because it doesn't even compile. After correcting the obvious

...

(lo, hi) <- getBounds buf

to

let (lo,hi) = bounds buf

The interface changed between GHC 6.4.2 and 6.6. But no honorable Haskell paladin would ever dare to use UndeadArrays.

it just works and needs 40MB plus epsilon. Your problem has to be somewhere else.

The strictness analyzer likes Udo more than Niko, does it? Regards, apfelmus
