Does it work on a non-Windows platform?
seems so; I've tried the example on Linux/x86_64 with GHC 7.8.0.20140228: {{{ $ ghc -O2 -rtsopts --make t.hs [1 of 1] Compiling Main ( t.hs, t.o ) Linking t ... $ ./t +RTS -s -K4G -RTS 257000000 33024500128500000 4,268,393,264 bytes allocated in the heap 172,568 bytes copied during GC 2,146,986,848 bytes maximum residency (12 sample(s)) 21,224 bytes maximum slop 4203 MB total memory in use (65 MB lost due to fragmentation) Tot time (elapsed) Avg pause Max pause Gen 0 8130 colls, 0 par 2.98s 2.98s 0.0004s 0.0004s Gen 1 12 colls, 0 par 1.69s 1.70s 0.1414s 0.7621s INIT time 0.00s ( 0.00s elapsed) MUT time 2.20s ( 2.20s elapsed) GC time 4.67s ( 4.68s elapsed) EXIT time 0.17s ( 0.17s elapsed) Total time 7.04s ( 7.05s elapsed) %GC time 66.3% (66.4% elapsed) Alloc rate 1,936,992,267 bytes per MUT second Productivity 33.7% of total user, 33.7% of total elapsed }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8839#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
