#11153: building lens-4.12.3 impossible happened: dupe _hs_primitive_memcpy --------------------------------------+---------------------------------- Reporter: blippy | Owner: Type: bug | Status: infoneeded Priority: normal | Milestone: Component: libraries (other) | Version: 7.10.2 Resolution: | Keywords: Operating System: Windows | Architecture: x86 Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | --------------------------------------+---------------------------------- Comment (by Phyx-): Is this still the case with `GHC 8.0.1`? Could you output the trace from that? The duplicate error message has been improved to show where both symbols come from. That should help diagnose this. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11153#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
