#13803: Panic while forcing the thunk for TyThing IsFile (regression) -------------------------------------+------------------------------------- Reporter: inaki | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1-rc2 Resolution: | Keywords: hs-boot Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): It also means that less work is done (and perhaps even fewer interface files read, which is big) if the axiom is never actually needed. So it might be ''more'' efficient. Not reading interface files too eagerly is one of the original reasons for the whole `forkM` story in `TcIface`. Would you like to try? Please comment the change, with a reference to this ticket. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13803#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
