[GHC] #15064: T8089 mysteriously fails when GHC is built with LLVM
#15064: T8089 mysteriously fails when GHC is built with LLVM -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.2.2 (LLVM) | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- CircleCI's LLVM build revealed that `T8089` fails. The test is quite simple, {{{#!hs main = threadDelay maxBound }}} and is expected to timeout. However, it somehow exits with code 0 in all ways when built with LLVM. This didn't reproduce when I tried `make test TEST=T8089 EXTRA_HC_OPTS=-fllvm` locally, so either it's a library issue or environment-sensitive. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15064 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
