#8980: ghc-7.8.1 -O2 eats excessive amounts of RAM, highlighting-kate and pandoc- citeproc ------------------------------------+------------------------------------- Reporter: slyfox | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.1 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- It's mostly a http://www.haskell.org/pipermail/ghc- devs/2014-March/004363.html rechecked on ghc-7.8.1: I attempted to leave original packages as-is. Steps to reproduce: {{{ $ cd /tmp/ $ wget -c http://code.haskell.org/~slyfox/selfcontained-eater- ghc-7.8-rc2.tar.gz $ tar -xzf selfcontained-eater-ghc-7.8-rc2.tar.gz $ cd selfcontained-eater-ghc-7.8-rc2 $ ./mk.sh ... [279 of 452] Compiling Text.Highlighting.Kate.Syntax.Asp ( highlighting- kate-0.5.6.1/Text/Highlighting/Kate/Syntax/Asp.hs, highlighting- kate-0.5.6.1/Text/Highlighting/Kate/Syntax/Asp.o ) stack overflow: use +RTS -K<size> to increase it }}} I did prepare this testcase for ghc-7.6.3 where it failed only on last 452 module. '''./mk.sh''' is a dumb script calling '''ghc -O2''' + cabal-generated bits. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8980 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
