#9078: Segfault with makeStableName -------------------------------------+------------------------------------ Reporter: robertce | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by ezyang): I believe the bug is when we free stable-name entries (in gcStableTables), we also need to remove the stable name from the hash table. updateStableTables will not catch this because it only iterates over live stable names. The bug is masked because if we immediately make another stable pointer, it will probably be put in the right slot, but the ASSERT catches the problem immediately. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9078#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
