I tried this, with ghc-4.08.1 -O both with and without profiling, on a Sparc box of I believe around 300 MHz, and I can't reproduce it at all. Without profiling, it allocates about 505 k of heap and runs in 0.02 seconds.

Ummm ?

I didn't use any optimizations, but I am sure that passing -O to ghc will make it see that 1*1*... is a constant expression. I guess turning all optimizations off is not the right way to test stuff either. Jan
