Description
In boost.cpp line 1129
int _buf_size = (params.boost_type LOGIT) || (params.boost_type GENTLE) ? data->sample_count*sizeof(int) : 0;
needs to be changed to
size_t _buf_size = (params.boost_type LOGIT) || (params.boost_type GENTLE) ? data->sample_count*sizeof(int) : 0;
otherwise boost is unable to train a classifier for a large amount of training points.
Associated revisions
fixed potential buffer size overflow in Boost::update_weight, bug #1524 (thanks to benlemna for the patch)
