#8777: Ghc crashes when compiling happstack-server on ubuntu-docker -------------------------------------+------------------------------------ Reporter: timthelion | Owner: Type: bug | Status: closed Priority: low | Milestone: Component: Compiler | Version: 7.4.1 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Changes (by monoidal): * status: new => closed * resolution: => fixed Comment: Closing as 'fixed' since the issue is fixed in upcoming template- haskell-2.9: https://github.com/ghc/packages-template- haskell/commit/d7b864b7ddb0e8c2f58d08dfd50e843eb8966b90 However, that fix will be present only in GHC 7.8, AFAIK 7.6 (or 7.4) is not going to have another bugfix release. Probably you can pester happstack's maintainers, a workaround should be easy. PS. Regarding reproduction: `pprExp 0 (CompE [])` in GHCi with TH should work. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8777#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
