I defined an infinite list of integers in the following way: -- increment a list of integer by one incl :: [ Integer ] -> [ Integer ] incl [] = [] incl (x:l) = (x+1:(incl l)) -- infinite list of integers il = ( 1 : (incl il)) the list prints nicely, however ghc has problems with this simple pattern-matching extraction of the first element: *Main> let (a:x) = il in a ghc-6.0: panic! (the `impossible' happened, GHC version 6.0): getLinkDeps No iface for [<pkg>]GHCziErr Please report it as a compiler bug to glasgow-haskell-bugs@xxxxxxxxxxx, or http://sourceforge.net/projects/ghc/. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=108032&aid=753377&group_id=8032
