Unexpected loop
The attached program executes as expected if compiled with GHC 7.0.3, but crashes with <<loop>> for GHC 7.4.1. When the code was more polymorphic (before simplifying the case), it just hanged. I suspect that the loop is related to the class dictionaries creation/passing.
Expected:
"1"
"1"Actual:
"1"
