#7126: Unexpected loop
-----------------------------------------+----------------------------------
Reporter: boris | Owner:

-----------------------------------------+----------------------------------
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"
bug: <<loop>>
}}}
