#7655: 7.6.2 Segmentation Fault/Bus Error in large exponentation -------------------------------------+---------------------------------- Reporter: Doug310 | Owner: Type: bug | Status: infoneeded Priority: normal | Milestone: 7.8.4 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: Differential Revisions: | -------------------------------------+---------------------------------- Comment (by rwbarton): So GMP 6 has (as I mentioned above) a macro to allocate small blocks with `alloca` and large blocks with `malloc`. The current release does not correctly use this macro in the code in question, but [https://gmplib.org/repo/gmp-6.0/rev/84965a50fd92 this backported patch] fixes this. So if we wait for GMP 6.0.1 and then update the in-tree tarball, this should get fixed automatically. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7655#comment:33 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
