Several months late I now have a simple test case for what I think is
either a GHC bug or a "misexpectation" on my part. This is with GHC
6.8.1 and I've tested both under Linux and MacOSX. It took a while to
reproduce it because I thought the problem had gone away, but actually
I'd just misunderstood when it happens. Here's a transcript of a
complete session with a shell to make it easy to reproduce. Note how
on the second run, ghci behaves differently.
--------------------------------------
> cat > bug.hs
x = 1
main = do
print x
> ghci bug.hs
GHCi, version 6.8.1: http://www.haskell.org/ghc/ :? for help
Loading package base ... linking ... done.
[1 of 1] Compiling Main ( bug.hs, interpreted )
Ok, modules loaded: Main.
*Main> main
1
*Main> x

*Main> :q
Leaving GHCi.

> ghci bug.hs
