#8281: The impossible happened: primRepToFFIType -------------------------------------+------------------------------------- Reporter: tibbe | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.4.1 Component: Compiler | Version: 7.6.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonmar): @winter it's always wrong to pass an unpinned `ByteArray#` to a foreign call, regardless of whether the call is annotated as `safe` or `unsafe`, because GHC is free to implement an `unsafe` call as a `safe` call. Indeed we do this in GHCi. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8281#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
