Hi all!.
I modified build.mk in order to allow Ticky-Ticky profiling (GhcLibWays=t). Now, when I try to make I get this error:

------------------------------------------------------------------------

== make way=t all;
PWD = (the_whole_path)/ghc-6.6.1/rts

ghc-6.6.1: panic! (the 'impossible' happened)
  (GHC version 6.6.1 for i386-unknown-linux):

        ToDo: tickyAllocThunk

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

Any clue?
Thanks in advance.
