#10288: -flate-dmd-anal triggers "Entered absent arg" -------------------------------------+------------------------------------- Reporter: yongqli | Owner: Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime crash | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by simonpj): Good news. I think this is fixed. At least I can't reproduce your crash with HEAD. I think that one of these two fixes has solved it: * #10218 * #10148 Both are merged to the 7.10 branch and so will appear in 7.10.2. It would be good if you were able to test that the 7.10 branch is indeed fixed in your case. I will try to do the same. Simon PS: for "entered absent arg w_sJ66e" bugs, compile with "-ddump-simpl" and grep for that string. That will show exactly which thunk in which function is being entered, and might save time compared to delete/recompile. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10288#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
