#13916: Optimizations create run time seg faults -------------------------------------+------------------------------------- Reporter: newthin | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 (CodeGen) | Resolution: | Keywords: optimization Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Indeed a `FUN` closure is being passed to `GHC.IO.Handle.hIsClosed`, which expects a `Handle`. `hIsClosed` then later calls `GHC.IO.Handle.Internals.do_operation`, which in turn calls `takeMVar`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13916#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
