Hmm yes, this is indeed rather unhelpful. I can explain why it happens, though. The compiler has lifted out the error case into a top-level binding:
x = error "Error in array index"
Would the compiler be less agressive with this if I turn off optimization? I usually use optimization with profiling as well, but could of course turn it off if it would result in more useful stack backtraces.
Possible... but not guaranteed. I think the simplifier does limited forms of let-floating even without -O. Cheers, Simon
