Segmentation fault when run examples

In ex1&2,run run.sh, I got these:

• exe_train=../../bin/forest_train
• exe_predict=../../bin/forest_predict
• trn=inputs/madelon.train
• tst=inputs/madelon.test
• model_rgf=outputs/model-rgf
• prediction=outputs/prediction
• orig_format=y.sparse
• save_freq=200

It maybe caused by wrong compiling or just code itself? How to solve it?

uncomment this set(CMAKE_CXX_FLAGS "-O3 -std=c++11 -pthread") to compile, will solve it~
