-fgenerics bug

I've discovered a simple fgenerics program that GHC doesn't like. Compiler output is as follows:

$ ghc --make gen-bug.hs Chasing modules from: gen-bug.hs Compiling Main ( gen-bug.hs, gen-bug.o ) ghc-6.4.2: panic! (the `impossible' happened, GHC version 6.4.2):

TcClassDecl: Type Application!

Please report this as a compiler bug. See:
