I saw your post on haskell-cafe and the answer from Simon Marlow. So there
seems to be a bug on Windows which is fixed now. However, I’m not sure
whether this fixes the problem with Grapefruit and garbage collection
completely since I experienced problems also on Linux.
I’m not having the time at the moment to do experiments using my insufficient
profiling skills. So could you please assist me a bit? As I told you, heap
profiling always gave me a single band for
Internal.Signal.Discrete.Vista.CAF. How can I split this monolithic band into
smaller ones that let me see where exactly the space is being leaked?
