System: Redhat 5.1 with all updates, Linux 2.1.125, glibc 2.0.7,
Dual Pentium II 300Mhz, egcs 1.1b compiler with PGCC patches.
GHC: GHC-4.00 binary distribution installed in /opt/ghc-4.00.
Trying to compile the following Haskell program
----------------------------------
module Main where
data Foo = forall a. MkFoo a (a -> Bool)
foo_list = [MkFoo 7 even, MkFoo True id]
f :: Foo -> Bool
f (MkFoo e p) = p e
main :: IO ()
main = putStrLn (show (map f foo_list))
----------------------------------
resulted in the following compiler output using the command
`ghc -fglasgow-exts -c Main.hs':
-------------------------------------
panic! (the `impossible' happened):
applyTypeToArgs Main.MkFoo{-r1l,x-} {B1 PrelBase.True{-6y,w-}}
Please report it as a compiler bug to

-------------------------------------
A minor modification for this program:
------------------------------------
module Main where
data Foo = forall a. MkFoo a (a -> Bool)
foo1 = MkFoo 7 even
main = putStrLn "foo"
------------------------------------
resulted in this compiler error (same command as before):
------------------------------------
panic! (the `impossible' happened):
lookupBindC:no info!
for: B1
(probably: data dependencies broken by an optimisation pass)
static binds for:
local binds for:
cZx
Please report it as a compiler bug to
