Strangely, this test allocates 16% less on 64-bit Windows, {{{ bytes allocated value is too low: (If this is because you have improved GHC, please update the test so that GHC doesn't regress again) Expected T10858(normal) bytes allocated: 241655120 +/-8% Lower bound T10858(normal) bytes allocated: 222322710 Upper bound T10858(normal) bytes allocated: 260987530 Actual T10858(normal) bytes allocated: 203567896 Deviation T10858(normal) bytes allocated: -15.8 % *** unexpected stat test failure for T10858(normal) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12713 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

This is a rather large deviation in the compilation of a program which really shouldn't have any appreciable platform dependence. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12713#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
