Program compiled with 7.4.1 runs many times slower than compiled with 7.2.2
The morfette program (http://hackage.haskell.org/package/morfette), when compiled with 7.4.1 runs extremely slow: approx. 20x times slower than when compiled with 7.2.1.
To reproduce, install morfette using both compilers, and run it on the attached `sample' file.
morfette train sample output --iter-pos=10 --iter-lemma=3
I attach the output of the profiler for both compilers. It would seem the performance bug is related to code from the modules GramLab.Perceptron.Multiclass and GramLab.Perceptron.Vector
