OK, this is quite annoying, it consistently fails when I do `cabal install -v`, but consistently succeeds when I do `cabal install -v3`! So with more verbose output you could build compdata. That you could do so consistently looks promising. Perhaps I missed laziness somewhere in my
#9186: GHC panic when compiling compdata -------------------------------------+------------------------------------- Reporter: snoyberg | Owner: simonmar Type: bug | Status: new Priority: high | Milestone: 7.8.4 Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: | Blocked By: None/Unknown | Related Tickets: #8935 Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by trommler): Replying to [comment:23 trommler]: patch for #8935.
I'll go check.
I rebased the patch for #8935 and cannot reproduce the issue for compdata version 0.8.1.0 and 0.9. I also built Haskell Platform [https://build.opensuse.org/project/show/devel:languages:haskell:platform] and pandoc [https://build.opensuse.org/project/show/devel:languages:haskell:pandoc] on OBS and did not see the issue. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9186#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
