It seems this was the case, thank you!

This simple implementation of CPU does not behave as expected in the
latest version of ghc using ST.Lazy since it updates the `pc` in the
wrong order.
When we use ghc-6.8 the code works as expected both with lazy and strict ST.
How is that? How do we fix this so we can use ghc-6.10.

e program is run like
runReaderT (loopSys 0)
which in turn is being runST'd and then printed
Does anyone know why the program just outputs <>
when compiled under ghc 6.10.2, and runs perfectly fine
under ghc 6.8.2? The program is compiled with --make and -O2
unusably slow:

Why does the program spend 96.1% of its total running time collecting garbage?
Any tips to make this program perform better are appreciated.
Please do tell if anything is unclear.
