#16017: ghc-8.6.1 and ghc-8.6.2 use a log of memory -------------------------------------+------------------------------------- Reporter: newhoggy | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.3 Component: Compiler | Version: 8.6.2 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: -------------------------------------+------------------------------------- Currently GHC uses a lot of memory to build a relatively small module and causes my CI to fail due to there being a 4G memory limit. The source code can be found here: https://github.com/haskell-works/hw- json/tree/73368cee21dc72eedd5291ba689f9abf10e7fcd2 The problem module is here: https://github.com/haskell-works/hw- json/blob/73368cee21dc72eedd5291ba689f9abf10e7fcd2/test/HaskellWorks/Data/Json/Backend/Standard/Succinct/CursorSpec.hs The build output follows: {{{ cabal new-build --enable-tests --enable-benchmarks --project- file="cabal.project" -j${CABAL_THREADS:-4} all Build profile: -w ghc-8.6.2 -O2 In order, the following will be built (use -v for more details): - hw-json-0.9.0.1 (lib) (first run) - hw-json-0.9.0.1 (test:hw-json-test) (first run) - hw-json-0.9.0.1 (exe:hw-json) (first run) - hw-json-0.9.0.1 (bench:bench) (first run) Configuring library for hw-json-0.9.0.1..
