#10245: panic in new integer switch logic with "out-of-range" literals -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: AndreasK Type: bug | Status: patch Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 7.11 (CodeGen) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Incorrect result | (amd64) at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4218 Wiki Page: | -------------------------------------+------------------------------------- Changes (by AndreasK): * status: new => patch Comment: I have a patch up on Phab but it increases allocations. (Phab:D4218) This seems to be caused by desugaring of derived constants. While the constants should be safe I don't see a way to differentiate them from user written constants. So I would appreciate input on the issue. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10245#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
