#11302: GHC HEAD uses up all memory while compiling `genprimcode` -------------------------------------+------------------------------------- Reporter: hvr | Owner: Type: bug | Status: closed Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 7.11 Resolution: duplicate | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #11303 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by heisenbug): Taking the hint from https://ghc.haskell.org/trac/ghc/ticket/11239#comment:5 I added `-fno- warn-overlapping-patterns -fno-warn-incomplete-patterns` to the compilation recipe like this: {{{ ghc -hisuf hi -osuf o -hcsuf hc -static -H64m -O0 -fasm -Wall -package-db libraries/bootstrapping.conf -hide-all-packages -i -iutils/genprimopcode/. -iutils/genprimopcode/dist/build -iutils/genprimopcode/dist/build/autogen -Iutils/genprimopcode/dist/build -Iutils/genprimopcode/dist/build/autogen -optP-include -optPutils/genprimopcode/dist/build/autogen/cabal_macros.h -package-id array-0.5.1.0 -package-id base-4.9.0.0 -XHaskell2010 -no-user- package-db -rtsopts -odir utils/genprimopcode/dist/build -hidir utils/genprimopcode/dist/build -stubdir utils/genprimopcode/dist/build -c utils/genprimopcode/./Main.hs -o utils/genprimopcode/dist/build/Main.o -fno-full-guard-reasoning -fno-warn-overlapping-patterns -fno-warn- incomplete-patterns }}} And it correctly built a `Main.o` and (subsequently on `make`) a `genprimopcode` so that I could go on bootstrapping. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11302#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
