#7919: Heap corruption (segfault) from large 'let' expression -------------------------------+-------------------------------------------- Reporter: duncan | Owner: simonmar Type: bug | Status: merge Priority: high | Milestone: 7.8.1 Component: Build System | Version: 7.6.3 Keywords: | Os: Linux Architecture: x86_64 (amd64) | Failure: Runtime crash Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | -------------------------------+-------------------------------------------- Changes (by simonmar): * component: Runtime System => Build System Comment: BTW, what you're doing is not likely to be fast :-) You have a constructor that is larger than a block, which will get copied around by the GC. Arrays and other large objects don't get copied, but we don't expect ordinary constructors/functions/thunks to be this big so they don't get the large object treatment. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7919#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
