#14379: Regression - GHC 2.8.1 Consumes All Memory On Build -------------------------------------+------------------------------------- Reporter: jm4games | Owner: (none) Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): 8.0.2 Wiki Page: | -------------------------------------+------------------------------------- Comment (by mpickering): Since Herbert merged the commit which made Semigroup a superclass of Monoid it became much more difficult to build packages with HEAD. https://phabricator.haskell.org/rGHC8ae263ceb3566a7c82336400b09cb8f381217405 The most reliable way I found now was to use the package overlay he posted about but it is more fiddly to set up. https://mail.haskell.org/pipermail/ghc-devs/2017-September/014682.html -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14379#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
