 I get an

 ghc-6.8.2: panic! (the 'impossible' happened)
   (GHC version 6.8.2 for i386-unknown-linux):
         nameModule poly_lookup'1_slSy{v}

 when compiling my module with -O2 and up.
 Before giving more details, i.e., going to the work of isolating the bug
 I'd like to know if there is an interest for this.
