#14135: PatternSynonyms regression in GHC HEAD (expectJust mkOneConFull) -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: dfeuer Type: bug | Status: new Priority: highest | Milestone: 8.4.1 Component: Compiler | Version: 8.3 Resolution: | Keywords: | PatternSynonyms Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3981 Wiki Page: | -------------------------------------+------------------------------------- Comment (by duog): Hope this isn't all obvious: Of the four flavours [quick, prof, devel2-stage1, devel2-stage2], only devel2-stage2 is compiled with -DDEBUG and hence has the failing assertion enabled. I would expect that commenting out the assertion would have devl2-stage2 succeed as well (or fail on another assertion!). Either the assertion is wrong, or it's problem is later corrected (since core lint passes). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14135#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
