#13433: Segmentation faults in profiled way -------------------------------------+------------------------------------- Reporter: bgamari | Owner: bgamari Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.1 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 bgamari): Quick update: At this point I have determined that the issue is the fix to #5642. Ultimately it seems like we are ending up with a `stg_sel_5_upd` being invoked on a `SimplEnv.FloatFlag`, which is not a single-constructor record (it is a enumeration). Naturally, things go terribly awry. Still trying to work out exactly how we get into this situation. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13433#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
