you can turn off let-floating by compiling without optimizations, i.e. without using a -O flag or using -O0 explicitly. The disadvantage is that most of all other optimizations are turned off too.

That is exactly what I'm doing at the moment. The module that has the nasty impure bits in it is not compiled with optimisations. I will improve this when GHC regains the non-let floating flag.

If you need -ffull-laziness to force a certain behaviour when using unsafePerformIO, I say that what you're doing is at the very least unsupported ;-) However, there are occasoinally good uses for this: HOOD is one; I imagine your case is similar? Cheers, Simon
