#8205: the 'impossible' happened : expectJust block_order ----------------------------------------+---------------------------------- Reporter: erikd | Owner: jstolarek Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC failed | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: ----------------------------------------+---------------------------------- Comment (by Jan Stolarek ): In [changeset:bec3c0497fa55e84005d175e0fc6b1d72df961e1/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="bec3c0497fa55e84005d175e0fc6b1d72df961e1" Drop proc-points that don't exist in the graph (#8205) On some architectures it might happen that stack layout pass will invalidate the list of calculated procpoints by dropping some of them. We fix this by checking whether a proc-point is in a graph at the beginning of proc-point analysis. This is a speculative fix for #8205. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8205#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
