#12425: With -O1 and above causes ghc to use all available memory before being killed by OOM killer -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: merge Priority: high | Milestone: 8.0.3 Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Inlining Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Compile-time | Test Case: performance bug | perf/compiler/T12425 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by erikd): I built a compiler from git HEAD, but that wouldn't build the dependencies for my library (numerous problems with the primitve and vector libraries). I tried checking out the `ghc-8.0` branch and then cherry-picking commit d03e41b4f5 but that failed due to merge conflicts in `compiler/simplCore/OccurAnal.hs` that seem rather tricky to resolve. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12425#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
