#15599: typeclass inference depends on whether a module is exposed. -------------------------------------+------------------------------------- Reporter: gleachkr | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.2.3 Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Linux | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by AndreasK): For another data point: On windows: {{{ $ bash test.sh Building project... These two results should be the same, since the only difference between the files is that one is an exported module *Tests.Good> Flag {checkFlag = True} *Tests.Bad> Flag {checkFlag = False} Here it is again with 8.4.3: Building project... *Tests.Bad> Flag {checkFlag = True} *Tests.Good> Flag {checkFlag = True} }}} The ghci script is hardcoded to linux paths so didn't work on windows. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15599#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
