#8316: GHCi debugger segfaults when trying force a certain variable -------------------------------------+------------------------------------- Reporter: guest | Owner: (none) Type: bug | Status: new Priority: high | Milestone: Component: GHCi | Version: 7.6.3 Resolution: | Keywords: debugger Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: GHCi crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): Simon, I implemented changes in `cvObtainTerm` as discussed yesterday, but I'm still getting "TSO object entered" errors. Previously `cvObtainTerm` follwed indirectee's of BLACKHOLEs no matter what. With my changes I only follow the indirectees when they're not TSO or BLOCKING_QUEUE. Somehow with this I still get "TSO object entered". If I don't follow BLACKHOLE indirectees at all (and bind a BLACKHOLE to `_t1` in this reproducer) then I get a deadlock as expected. Do you have any ideas on why this may be happening? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8316#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
