Segmentation fault with liblinear 2.11

[christoph-conrads]

train in liblinear 2.11 crashes for me after applying the change in #36. The console output is below; observe the iteration counter. Valgrind detected an out-of-bounds read in linear.cpp:75-83 (axpy()) and adding assert( y->index > 0 ); as the first statement in the while loop aborts the program on execution.
