#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: | -------------------------------------+------------------------------------- Changes (by osa1): * cc: osa1 (added) Comment: `mallocBytes` does a conversion from `Int` (signed) to `CSize` (unsigned). On 64bit Linux system `Word` and `CSize` have the same size so this function could use `Word` as argument, but I wonder if this is always the case. In any case I think the argument should be an unsigned type (`Word`, `CSize`, or something else). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14850#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
