#7126 closed bug (fixed)

Unexpected loop

Reported by: boris Owned by:
Priority: normal Milestone: 7.6.1

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.




bug: <<loop>>
