#5688: instance Read Integer/Rational/Double readsPrec out of memory and crash due to exponential notation -------------------------------------+------------------------------------ Reporter: gracjan | Owner: igloo Type: bug | Status: closed Priority: highest | Milestone: 7.4.2 Component: libraries/base | Version: 6.12.3 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: Runtime crash | Difficulty: Unknown Test Case: T7034 | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by hvr): I've been looking at [afcddc5ce033de84/base] which added the `Text.Read.Lex.Number` data type, and two functions to convert `Number` into `Integer` or `Rational`. However, the type `Number` wasn't exported (which caused a Haddock warning and caught my attention). Is there a reason not to export `Number` (without any constructor)? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5688#comment:66 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
