#9122: Make Lint check for bad uses of `unsafeCoerce` -------------------------------------+------------------------------------ Reporter: simonpj | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by simonpj): The rules are documented with `unsafeCoerce`, [http://www.haskell.org/ghc/docs/latest/html/libraries/ghc-prim-0.3.1.0 /GHC-Prim.html#v:unsafeCoerce-35- here]. It's pretty much guaranteed that coercing from, say `Int#` to `Int` will give rise to serious problems.
