My program compiles with -O1 but compiler panics with -O2 and up
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.
