#14497: internal error: scavenge_one: strange object 19828 -------------------------------------+------------------------------------- Reporter: Yuras | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.2.2 Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by Yuras): * cc: simonmar (added) * priority: normal => high * milestone: => 8.2.2 Comment: Then it is a regression, right? Please feel free to lower priority/change milestone if you disagree. I played with it a bit. Looks like it is not related neither to `ST`, no to concurrent evaluation of the same thunk. But resuming a thunk after blackholing is completely broken. Once I even got <<timeout>> exception thrown in each child thread. Disaster. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14497#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
