#11508: QuickCheck application hangs with concurrent read/write of Chan -------------------------------------+------------------------------------- Reporter: orion | Owner: Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 | (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by erikd): I just tried this on x86_64 Debian with ghc-7.10.3 (installed from Debian) and it seems to run fine. At the end I get {{{ 2 1 1 OK (10.16s) +++ OK, passed 100 tests. All 2 tests passed (20.32s) }}} Tried three runs without a single hang. Debian applies a couple of patches to the official GHC 7.10.3 tarball. Those patches are in the file http://ftp.debian- ports.org/debian/pool/main/g/ghc/ghc_7.10.3-7.debian.tar.xz . I've had a brief look at those patches, but none of them seem relevant to this issue. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11508#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
