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.
