debugger gives "Can't unify" when stopped at an exception
Presumably due to exceptions now using existential types, the GHCi debugger now gives:
ghc: panic! (the 'impossible' happened)
(GHC version 6.9.20080731 for x86_64-unknown-linux):
Can't unify
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabugwhen it stops at an exception. See break011 and break024 for testcases.
