#13458: Panic with unsafeCoerce and -dcore-lint -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler (Type | Version: 8.1 checker) | Keywords: Resolution: | LevityPolymorphism Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): I'm uncomfortable with restricting the type of `unsafeCoerce#`. What if someone wants to do something really dirty, like cast a `Float#` into a `Word#` just to see the bits? This would be prohibited by comment:10. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13458#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
