#7684: cgrun071 segfaults ----------------------------------+---------------------------------- Reporter: tibbe | Owner: leroux Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 (amd64) Type of failure: Runtime crash | Difficulty: Unknown Test Case: cgrun071 | Blocked By: Blocking: | Related Tickets: ----------------------------------+---------------------------------- Comment (by tibbe):

is the test using the fallback version (written in C?) or the slowpopcount one in the test itself?

The test is comparing the `hs_popcnt*` C implementation in ghc-prim with the `slowPopcnt` in the test itself. I don't see why `slowPopcnt` would segfault so probably we're generating the wrong call sequence to `hs_popcnt*` in the native code generator (I assume llvm isn't being used). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7684#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
