#2475: debugger gives "Can't unify" when stopped at an exception
------------------------+---------------------------------------------------
Reporter: igloo | Owner:
Type: bug | Status: new
Priority: normal | Milestone: 6.10.1
Component: GHCi | Version: 6.8.3
Severity: normal | Keywords:
Difficulty: Unknown | Testcase: break011, break024
Architecture: Unknown | Os: Unknown
------------------------+---------------------------------------------------
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/reportabug
}}}
when it stops at an exception. See `break011` and `break024` for
testcases.
