I cut and pasted your code into ghci-6.4.2 with -fglasgow-exts and there was no error. And I can (print (showSnd (Pair A True)) and (print (showSnd (Pair B 8))) but when I try to compile it with ghc-6.4.2 it complains about the Show instance. I find this deeply wierd, and it seems like a bug.

Thank you for this information. I've reported this as a bug now. Best wishes, Wolfgang
