#15087: Internal Error with Bibliography Profiling -------------------------------------+------------------------------------- Reporter: crockeea | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Runtime crash Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- When running my large program with `+RTS -hb`, I get the following error: {{{ internal error: Invalid object in processHeapClosureForDead(): 7 (GHC version 8.4.2 for x86_64_unknown_linux) }}} Unfortunately, I'm unable to find a minimal example. (Side note: I doubt this is relevant, but this is a multi-threaded program. I first tried to profile with `+RTS -N4 -hb`, but got `-hb cannot be used with multiple capabilities`. I assumed this means it doesn't like `-N4` with `-hb`, so I removed `-N4` and got the above error.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15087 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
