I'll work with Simon to investigate the runtime, but would welcome any ideas on further speeding up cafe4.
An update on this: with the help of Alex I tracked down the problem (an integer overflow bug in GHC's memory allocator), and his program now runs to completion.
So this was about keeping the program largely unchanged in order to keep the GHC issue repeatable for tracking? Or have you also looked into removing space leaks in the code (there still seemed to be some left in the intern/cafe5 version, iirc)?
I haven't touched the code - I'll leave that to the expertise of haskell-cafe! :) It would be nice to have a boiled-down version of this for a benchmark though. Cheers, Simon
