#10565: GHC 7.10.2 RC: the impossible happened on hPDB-examples-1.2.0.2 ---------------------------------+----------------------------------------- Reporter: snoyberg | Owner: bgamari Type: bug | Status: new Priority: normal | Milestone: 7.10.2 Component: Compiler | Version: 7.10.2-rc1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: ---------------------------------+----------------------------------------- Comment (by bgamari): I should note that the original testcase (found here https://github.com/bgamari/ghc-T10565/blob/master/Rg.hs) compiles with 7.10.1 yet not with 7.10.2. It does, however, compile with 7.10.2 if one uses a more reasonable implementation of `guessElement`. It is do wonder what changed between 7.10.1 and 7.10.2, however. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10565#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
