Just when you thought it's weekend: :-)
Here's another bug in the upcoming 4.02:
---------- Argl.hs --------------------------------------
import System
main = exitFailure
---------------------------------------------------------
panne@fangatau: > ghc-4.02 Argl.hs -O
panic! (the `impossible' happened):
IdInfo parse failed exitFailure
/mnt/fangatau1/svens-ghc-test/ghc-4.02/lib/ghc-4.02/imports/std/System.hi:59
Interface-file parse error; current input =
Please report it as a compiler bug to [EMAIL PROTECTED]
---------------------------------------------------------
Without -O everything is fine. Just for fun the offending line from
System.hi:
1 exitFailure :: __forall [a] => PrelIOBase.IO a {-## __A 1 __u \ __a a -> __coerce
(PrelIOBase.IO a) (\ _115 :: (PrelGHC.State# PrelGHC.RealWorld) -> case __ccall_GC
exit {__a (PrelGHC.State# PrelGHC.RealWorld -> PrelGHC.Int# -> (# PrelGHC.State#
PrelGHC.RealWorld #)) _115 1} of wild { (# ds #) -> __coerce (# PrelGHC.State#
PrelGHC.RealWorld, a #) (PrelException.ioError __a a _108_118_1084) }) ##-} ;
Cheers,
Sven
