#14619: Output value of program changes upon compiling with -O optimizations -------------------------------------+------------------------------------- Reporter: sheaf | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.6.1 Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 Type of failure: Incorrect result | (amd64) at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by mpickering): It seems to have been lost above but -fno-worker-wrapper fixes the issue. This seems to point to the implementation of unboxed tuples or Double# being the issue. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14619#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
