#11380: Compiling a 10.000 line file exhausts memory -------------------------------------+------------------------------------- Reporter: kennethb | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by thomie): `happy` has a `-a` flag: {{{ -a --array generate an array-based parser }}} Cabal calls `happy -agc` by default, but I was using just `happy` in comment:4. It seems to influence the results when trying to compile `Parser.hs` within 3GB RAM. || ghc-7.10.3 Parser.hs ||= happy =||= happy -a =|| || -O0 || not ok || ok || || -O1 || ok || ok || @jstolek: compiling the non-array based parser //without// optimizations fails. Very strange. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11380#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
