-fno-implicit-prelude -prof bug on x86

GHC 6.0 fails to compile this on x86 Linux with -fno-implicit-prelude 
-prof:

  module M where {}

$ ghc -fno-implicit-prelude -prof -c M.hs
/tmp/ghc4124.hc:5: `NULL' undeclared here (not in a function)
/tmp/ghc4124.hc:5: initializer element is not constant
/tmp/ghc4124.hc:5: (near initialization for `M_CAFs_cc_ccs[0].prevStack')
/tmp/ghc4124.hc:5: `NULL' undeclared here (not in a function)
/tmp/ghc4124.hc:5: initializer element is not constant
/tmp/ghc4124.hc:5: (near initialization for 
`M_CAFs_cc_ccs[0].indexTable')

It successfully compiles if either -prof or -fno-implicit-prelude is 
removed. It successfully compiles on MacOS X.
