I converted the xgboost binary classification model to C++ code, compiled it into an exe program, ran it on a large scale dataset and found that the program ran out of memory, the memory usage went up from the initial 30MB to 1.5GB, and then ran out of memory, and after debugging I found that it seems to be this line of code that causes the memory to keep increasing:

memcpy(output, make_array((1.0) - (var55), var55), 2 * sizeof(double));

This has now been resolved and was not caused by the generated code
