#7684: cgrun071 segfaults ----------------------------------+---------------------------------- Reporter: tibbe | Owner: leroux Type: bug | Status: patch 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 leroux): My fix is to simply apply a mask of n-bits to the word being passed to the fast population count function. After fixing the {{{popcnt8}}} test, I found that {{{popcnt16}}} also had the same problem, so I ended up applying the fix to 8, 16 and 32 bit word tests. {{{ test_popCnt8 = test (popcntMask 8 popcnt8) (slowPopcnt . wordMask 8) test_popCnt16 = test (popcntMask 16 popcnt16) (slowPopcnt . wordMask 16) test_popCnt32 = test (popcntMask 32 popcnt32) (slowPopcnt . wordMask 32) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7684#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
