Hi. I have composed a patch that implements Foreign.C.String according
to Foreign Function Interface Addendum, i.e. C strings are treated as
they are encoded with the current locale. Search Locale.hs in the
patch for further directions. Ask if you do not know how to build a

That works fine for my own stuff, but I'd like it to work for people

One issue that comes up is that when you fork a package, data can no
longer be freely exchanged between libraries using the original
package's datatypes and libraries using the forked package's
datatypes. Something that might help here is the concept of
extension or friend packages or modules:

can't speak as to how difficult it is to get GHC built unregisterised,
but you might want to consider JHC if you don't need to use a lot of
Hackage. It compiles to C without a special RTS needed, which might
make it a lot easier.

This works:

So does this:

You have to fix the type of 1 and 6, e.g. by writing
x - randomRIO (1, 6) :: IO Int
or
x - randomRIO (1, 6 :: Int)
GHCi defaults integral numbers to Int, that's why it works there.

Looks like the crash is due to ASLR (Address Space Layout Randomization).
You need to disable it for it to work. You can disable ASLR very easily -
