#14850: mallocBytes allows underflow -------------------------------------+------------------------------------- Reporter: wyager | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 8.0.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Poor/confusing | Unknown/Multiple error message | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by wyager): I agree, changing the argument type to Word is probably the most semantically sensible approach. It has the nice effect of shifting the responsibility of underflow detection to the caller. I think the ecosystem in general could benefit from a wide-ranging examination of whether “Int” is actually appropriate (indexing, lengths, etc.). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14850#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
