#15646: ghci takes super long time to find the type of large fractional number -------------------------------------+------------------------------------- Reporter: Johannkokos | Owner: | JulianLeviston Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: GHCi | Version: 8.4.3 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Hmm, interesting. I would first start by running GHC with `-v3` to make sure that the cost is still showing up in the same place. I would then try to build a profiled compiler and see more precisely where things are blowing up. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15646#comment:47 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
