Okay, I know I promised that was the last one, but you can actually get
it simpler. Remove all the dynamic map stuff. Just have two files,
Range.hs and Coref.hs, with:
module Range where
import Data.Dynamic
data Range = Single Int
| Range Int Int
deriving (Eq, Ord, Show)
Okay, this is the last spam from me.
Here's exactly what you need to do to get the bug.
Create three modules, DynamicMap.hs, Range.hs and Coref.hs, containing
the following:
DynamicMap.hs
module DynamicMap
( DynamicMap,
emptyDM,
addToDM,
foldDM
This hasn't yet been posted, but I've actually whittled it down quite a
bit.
All we need is to import the Util.DynamicMap and do:
> dm1 = addToDM emptyDM (Range 1 2)
> showDM :: DShow -> DynamicMap -> ShowS
> showDM sd = foldDM (\d b -> case sd d of { Nothing -> b ; Just s -> s
. b }) id
and do

i'm experiencing a problem when trying to compile the CVS tree of ghc.
i've COed from the cvs the modules "fpconfig", "ghc" and "libraries".

and set up mk/build.mk (taken from mk/build.mk.sample)

Hi Simon,
Forget about this one!
It's as with the dentist: If you go there, the ache vanishes.
I tried to assemble a distribution for you, everything worked fine.
When I compiles the stuff yesterday, I only "touched" the .hs-source.
Perhaps some old .hi-files caused the problem.

If you get into a state where --make produces a crashing program, then
it's a good idea to take a snapshot of

Hi Wolfgang,
Thanks again for the prompt reply.
I did exactly as you noted below (removed the framework support check
from configure.in,
ran autoconf and ./configure, then built. Everything works appears to
work correctly but
ghci. (For example, I can build a network test program that queries

Both of the above. :-)
There is something really fishy going on; I checked out the same code
in a different directory, and built it in the same way, without
getting the same behaviour.
I'm not quite sure wha

I should note that I've done
the build without Wolfgang's HaskellSupportFramework, by setting the
include
and library paths in build.mk. This is more compatible with the
automated packing
scheme of DarwinPorts.
Of course. The HaskellSupport.framework isn't necessary when the user
already has Dar
A known infelicity; see the bottom of
http://www.haskell.org/ghc/docs/latest/html/users_guide/bugs.html
My hypothesis is that this only happens if you try to make it happen.
I've never found it happen in a real program. Let me know if that's not
the case.
