XBART.CLT std::bad_alloc error, R

[mm0708]

When attempting to use XBART.CLT for binary classification I get the following error:

Error in XBART_CLT_cpp(y, X, Xtest, num_trees, num_sweeps, max_depth, : std::bad_alloc

Seems to be a C++ error in the backend? I do not encounter this error when running XBART() on the example found here: https://github.com/JingyuHe/XBART/blob/master/tests/test.R
