okay, tried again with the 5.00.2 package; same behavior:
Glasgow Haskell Compiler, Version 5.00.2, for Haskell 98, compiled by GHC version
5.00.2
Using package config file: /usr/lib/ghc-5.00.2/package.conf
Hsc static flags: -static -fignore-interface-pragmas -fomit-interface-pragmas
-fdo-lambda-eta-expansion -flet-no-escape
*** Ineffective C pre-processor
echo '{-# LINE 1 "Y.hs" #-}' > /tmp/ghc6092.hspp && cat Y.hs >> /tmp/ghc6092.hspp
*** Checking old interface for hs = Just "Y.hs", hspp = Just "/tmp/ghc6092.hspp":
Compiling Y ( Y.hs, Y.o )
*** Parser:
*** Renamer:
*** Typechecker:
*** Desugar:
Result size = 76
*** Simplify:
Removing: /tmp/ghc6092.hspp
It gets stuck just after it prints "*** Simplify:" and consumes all available
memory until I hit Ctrl-C.
The file, again, is the following:
---begin Y.hs---
module Y
(y, fact, factorial)
where
data D a = D ((D a) -> a)
unD :: D a -> D a -> a
unD (D g) = g
y :: ((a -> a) -> a -> a) -> a -> a
y = \f -> let
z = \g -> f ((unD g) g)
in
z (D z)
fact :: (Integer -> Integer) -> Integer -> Integer
fact = \factt -> \x -> if (x == 0) then 1 else x * (factt (x-1))
factorial :: Integer -> Integer
factorial = y fact
---end Y.hs---
