This issue should now be gone:

valgrind --track-origins=yes bin/rf-ace-build-predictor -I 
issue19/Datasets/adult/adult.test.arff -i class -O gbt_issue19.sf

Confirm. (But for given data set rf-ace ran more than 10 minutes and I killed 
it. It is weird on such small data...)

True, I noticed as well that the latest changes are oddly making the program 
run slower. I will investigate the reason for this behavior.

With the latest revision (r463) here are the time consumptions of different 
operations:

bin/rf-ace-filter -I issue19/Datasets/adult/adult.test.arff -i class -O 
issue19/associations.tsv
...
105.26 seconds elapsed.

bin/rf-ace-build-predictor -I issue19/Datasets/adult/adult.test.arff -i class 
-O issue19/gbt.sf
...
7.59 seconds elapsed.

bin/rf-ace-predict -F issue19/gbt.sf -I issue19/Datasets/adult/adult.test.arff 
-O issue19/predictions.tsv
...
1.16 seconds elapsed.

NOTE: prediction may give inaccurate results due to partially working forest 
(.sf) loader.
