Ticket #150 (closed bug: Fixed)
ghc-6.0: panic on a simple example
|Reported by:||fraczak||Owned by:||nobody|
|Type of failure:||Difficulty:|
|Test Case:||Blocked By:|
I've just installed ghc-6 and started to play with it. 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 firstname.lastname@example.org, or http://sourceforge.net/projects/ghc/.
