#10176: Invalid core generated with GHC 7.10 RC3 -------------------------------------+------------------------------------- Reporter: NeilMitchell | Owner: Type: bug | Status: new Priority: high | Milestone: 7.10.1 Component: Compiler | Version: 7.10.1-rc3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by hvr): not sure if this is useful information, but I compared the output of {{{ ghc -fforce-recomp -outputdir obj -O -ddump-simpl -dsuppress-uniques Buggy.hs }}} for acbfc19a6d27b51aaec5177e4b64ea9b45f74c84 (recent ghc-7.10 branch snapshot) vs. 029a296a770addbd096bbfd6de0936327ee620d4 (one commit before the big typeable-change that caused `shake-test oracle test` to start failing) And well, the Core output looks just the same, so I'm not sure if the `Buggy.hs`/`Errors.hs` test-case highlights the same issue causing `shake- test` to fail. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10176#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
