#9407: Program produces different output when compiled with -O -------------------------------------+------------------------------------- Reporter: arotenberg | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 (amd64) Type of failure: Incorrect | Difficulty: Unknown result at runtime | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by arotenberg): I have now also verified that this problem does ''not'' occur on 32-bit Windows nor when using 32-bit GHC on 64-bit Windows. But you should be able to reproduce it if you use 64-bit Windows and 64-bit GHC 7.8.3. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9407#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
