So I am not sure if this is a bug in Criterion itself, the Statistics package or any dependency or if I am doing something obviously wrong. I would be grateful if someone could look into this as it is holding me back from using Criterion for benchmarking my code.
I would suspect Statistics.Resampling.resample. From quick glance criterion doesn't use any concurrent stuff. I'll try create smaller test case
It looks like I'm wrong. I obtained event log from crashing program and resample completed its work without problems. Crash occured later. Next suspect is bootstrapBCA itself. It uses monad-par to obtain parallelism[1].
I tried to create smaller test case without any success.

Replacing "runPar $ parMap" with a simple "map" on that line seems to fix the bug. At least I could not reproduce it anymore on several runs with my original test case. So it seems to be a bug in the Par monad package as this change shouldn't alter the program's behaviour, should it? Regards, Till
