morfette-0.3.4 compiled with ghc 7.4.1 runs extremely slowly.

Some further details.

The following command:
./bin/morfette train --dict-file 
/data/gchrupala/data/corpora/freeling-dict/dicc-2.0.src --language=es 
--iter-pos=10 --iter-lemma=3  
/data/gchrupala/data/corpora/ancora-morfette/train.tokpos 
data/ancora-morfette-0.3.1-i10x3.model

Using:
morfette-0.3.2, compiled with ghc 7.2.2
Linux cl6lx 2.6.31.5-0.1-desktop #1 SMP PREEMPT 2009-10-26 15:49:03 +0100

Killed as it seems stuck.

So this is an issue with ghc 7.4.1 (or some associated libraries)

Latest news this is that this is a performance regression in the array library:

Until this is solved, do no use compile morfette with ghc-7.4.1.
