#15114: ghc 8.4.1 optimizes True to False -------------------------------------+------------------------------------- Reporter: elaforge | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): I think the bug also does not manifest in GHC 8.2.2. It's probably already-fixed, but at least it's an excellent regression test. And I'd like to be sure that it really IS fixed, rather than merely concealed, in 8.4.2. Does anyone feel able to bisect to the commit that fixes it? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15114#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
