#10571: GHC 7.10.1 segfaults when shiftL-ing Integers by negative amounts -------------------------------------+------------------------------------- Reporter: anders_ | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 Type of failure: Runtime crash | (amd64) Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton): Might not be possible inside integer-gmp for dependency reasons (`error` is defined in base which depends on integer-gmp) but certainly possible in the instance in Data.Bits. Having `shiftLInteger` itself crash on negative shifts is fine IMHO as it's not intended for end-user use. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10571#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
