Just to say this bug is now fixed in both the head
and stable branches.

| |
| |
| | Hello. Given the source:
| |
| |
| | module GHCITst where
| |
| | data Q = forall x . Show x => Q x
| |
| | showQ (Q x) = show x
| |
| |
| | GHCi behaves like this:
| |
| | ___ ___ _
| | / _ \ /\ /\/ __(_)
| | / /_\// /_/ / / | | GHC Interactive, version 5.01, For
| | Haskell 98.
| | / /_\\/ __ / /___| | http://www.haskell.org/ghc/
| | \____/\/ /_/\____/|_| Type :? for help.
| |
| | Loading package std ... linking ... done.
| | Prelude> :l GHCITst
| | Compiling GHCITst ( GHCITst.hs, interpreted )
| | Ok, modules loaded: GHCITst.
| | GHCITst> showQ (Q "foo")
| | Segmentation fault
| |
| |
| | The behavior is the same for 5.00. Tested both on
| | debian-unstable, linux 2.4.4, glibc-2.2.2, gcc-2.95.4 and
| | redhat 6.1, linux-2.2.19, glibc-2.1.3, egcs-1.1.2.
| |
| | Prithee, somebody fix this, I would _so_ love to migrate from
| | hugs and get all the yummy ghc extensions and hslibs when
| | using an interpreter. :)
