Interesting. ----- Forwarded message from Neal Alexander ----- Date: Tue, 21 Jul 2009 18:48:38 -0700 From: Neal Alexander To: haskell-cafe@haskell.org Subject: [Haskell-cafe] System.Mem.performGC leaks? main = forever performGC The OS reported memory usage skyrockets. If i enable +RTS -S the GC statistics show the heap "live bytes" being constant. Is it accumulating statistics even when profiling is disabled (and can you turn that off), or is there something going on with the FFI call to performGC. Compiled with "ghc -O2 -fvia-C -optc-O2 -funbox-strict-fields -threaded" btw. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe ----- End forwarded message -----
