matrix_test and score_test fail on linux

[Peter]

Test fail on my pristine checkout too.

This probably some problem with the vector class. I get the following assertions

gsl: /usr/local/include/gsl/gsl_vector_double.h:200: ERROR: index out of range
Default GSL error handler invoked.
FAIL: matrix_test

lt-score_test: AUC.cc:81: virtual double theplu::yat::statistics::AUC::score(const theplu::yat::classifier::Target&, const theplu::yat::utility::VectorBase&, const theplu::yat::utility::VectorBase&) const: Assertion `target.size()==value.size()' failed.
FAIL: score_test

Now also knn_test fails with GSL reporting out of range.

added test test program for view in [1114]

On my linux machine the output becomes:

First
f aa: 7 8 9
f bb: 
Second
f aa: 7 8 9
f bb: 
Third
f aa: 7 8 9
f bb: 7 8 9
Fourth
f aa: 7 8 9
f bb: 
data 2:
1
1
1

which is quite different when running it on Mac.

I guess all of this indicates that there is a pointer that is not properly initialized?
