GHCi cannot safely continue in this situation. Exiting now. Sorry. }}} (Full log at https://buildd.debian.org/status/fetch.php?pkg=yi&arch=kfreebsd-i386&ver=0.7.1-3&stamp=1410882226) It does not happen on amd64. This happens on the Debian auto-builders and I did not reproduce it locally yet, but maybe someone can already tell me what’s wrong from looking at it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9657 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
