Stack overflow in criterion

Test program:

import Criterion.Main
main = defaultMain [bench "id" $ whnf id ()]

When I compile and run this with 7.1.20110517, I get:

warming up
estimating clock resolution...
mean is 2.896519 us (320001 iterations)
Stack space overflow: current size 8388608 bytes.
Use `+RTS -Ksize -RTS' to increase it.

This doesn't happen with 7.0.3.
