Thanks for working on this. I haven't been following this issue, but is
#7719: System.Timeout.timeout may leak <<timeout>> exceptions -------------------------------+-------------------------------------------- Reporter: int-e | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 7.7 Keywords: | Os: Linux Architecture: x86_64 (amd64) | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | -------------------------------+-------------------------------------------- Comment(by int-e): Replying to [comment:12 igloo]: there a patch that you think should be applied now? And is there a test that it fixes? I've implemented a testcase now, based on the sample program above; the patch that should definitely be applied is the minimal [attachment:0001 -Fix-System.Timeout.timeout-leaking-Timeout-exception.patch] one. The second patch is about improving performance and needs a second pair of eyes. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7719#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
