#7655: 7.6.2 Segmentation Fault/Bus Error in large exponentation -------------------------------+---------------------------------- Reporter: Doug310 | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: GHCi | Version: 7.8.1-rc1 Resolution: | Keywords: exponentiation Operating System: MacOS X | Architecture: x86_64 (amd64) Type of failure: GHCi crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------+---------------------------------- Comment (by hvr): btw, note that `(^)` for `Integer` is implemented via square-and-multiply, c.f. [http://hackage.haskell.org/package/base-4.6.0.1/docs/src/GHC- Real.html#%5E implementation in base]. So it might be interesting if one could find out which one of the several `Integer`-primop calls involved causes the actual fault. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7655#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
