<p>The program is attached in this mail, along with stack & cabal config. The machine is an old T400 with an Intel dual core.<br>

Followin some advice, I checked the output of `+RTS -s` and apparently sometimes one of the sparks is fizzled which is what causes the unexpected behaviour</p>

* what is your actual cabal / stack config file?<br>
* on what machine (OS, CPU) are you running this (it seems pretty slow)?<br>
* have you looked at eventlogs with threadscope?<br>
