#15617: Unboxed tuples/sum error message on `a = show 5` in expression evaluation and interactive modes -------------------------------------+------------------------------------- Reporter: ChaiTRex | Owner: | JulianLeviston Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.6.1-beta1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Poor/confusing | Unknown/Multiple error message | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by osa1): * cc: RolandSenn (added) Comment: I think you're right. This is another example of problems caused by not having the information of whether we're in interpreter or not in the compiler (we only have information derived from the flags but that information can't tell reliably whether we're in interpreter, as in this ticket). @RolandSenn has a good summary of the problem in Phab:D5122 which also links to a few other issues caused by this problem. Perhaps we should do the refactoring to add a field to DynFlags about whether we're in interepreter. If we do this then maybe we should revisit some of the fixed tickets and fix them "properly" by using the new field. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15617#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
