#14730: Missing predicate for "ResourceVanished" IOException/IOErrorType -------------------------------------+------------------------------------- Reporter: bit | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 8.2.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by vdukhovni): Also, perhaps the use of strerror(3) in "Foreign.C.Error" rather than strerror_r(3) is not entirely thread-safe under atypical conditions. If the kernel is newer than the C-library, it may return error numbers that lie outside the static string array used by strerror(3) and friends, and in that case, strerror(3) will use a static buffer to generate "Unknown error: <number>", but use of that buffer is not thread-safe. For this to be a problem, two threads have to encounter two different unknown to the C-library errors at essentially the same time. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14730#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
