#13970: Segmentation fault inside threadPaused -------------------------------------+------------------------------------- Reporter: albertov | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 8.2.1-rc3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by albertov): After removing many dependencies and some cleanup we've opensourced the engine of the problematic wildfire simulator. Fortunately the bug still manifests itself (which rules out some kind of nasty interaction with the foreign libraries it linked to). To reproduce clone https://github.com/meteogrid/propag , `cabal new-build` it and run the `propag-demo` executable. Using the rc3 pre-release and running with `+RTS -N12` it crashed 100% of the times I've tried (the refactor has increased the change of crash). Sorry for this monster of a reproducible case. It's the best I could do to minimize the amount of third-party dependencies for the time being. I'm planning to remove the dependency on the wildfire-specific stuff which should remove more dependencies (and make it useful as an arbitrary 2D spread automata). I've tried initially to reproduce it starting from scratch but did not succeed so I pulled out all the bigger dependencies (eg: meteogrid/bindings-gdal) which require bindings to c++ libraries. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13970#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
