How to reproduce roughly: {{{ $ cd utils/genprimcode $ alex --ghc Lexer.x $ happy --ghc Parser.y $ ghc-7.11.20151226 --make Main [1 of 5] Compiling ParserM ( ParserM.hs, ParserM.o ) [2 of 5] Compiling Lexer ( Lexer.hs, Lexer.o ) [3 of 5] Compiling Syntax ( Syntax.hs, Syntax.o ) [4 of 5] Compiling Parser ( Parser.hs, Parser.o ) [5 of 5] Compiling Main ( Main.hs, Main.o ) ...killed by OS due to running out-of-memory after using up >10GiB ram.... }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11302 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
