impossible happened

when I try to compile http://hpaste.org/2772 I got:

$ ghc --make xmltr.hs -o xmltr
[1 of 1] Compiling Main             ( xmltr.hs, xmltr.o )
ghc-6.6.1: panic! (the 'impossible' happened)
  (GHC version 6.6.1 for x86_64-unknown-linux):
        initC: srt

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