It is not affected by optimization level. The `NOINLINE` is essential, as is using something that handles a `State#` token—substituting another unboxed type like `Int#` in its place does not cause this problem. Using `undefined` or `s` instead of `s'` in the return value makes the problem go away.

A while back, I asked whether `seq#` was really necessary to implement `evaluate`. I was trying to figure out if sufficient `NOINLINE` use would be able to avoid it. I was a bit surprised to crash the compiler! The example given is only slightly stripped down from my initial experiment. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9964#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I may have found a way to reliably reproduce this bug using real code:
Well you are reliably producing ''some'' bug, but I think it's pretty unlikely that it is the subject of this ticket! Does it happen with the 7.10 release candidate?
