将swig重命名为ocaml时出现的奇怪行为

我观察到奇怪的重命名行为 我将swig应用于ocaml代码,并复制了这些代码 关于swig官方示例代码( https://github.com/swig/swig/blob/master/Examples/ocaml/std_vector )此处:

实例h类

#include <vector>
#include <stdexcept>
#include <numeric>

double average(std::vector<int> v) {
    # instead of calculating the average,
    # throw an invalid_argument
    throw std::invalid_argument("test");
    return 0;
}

实例i(与上面链接中的相同)

%module example

%{
#include "example.h"
%}

%include stl.i
/* instantiate the required template specializations */
%template(IntVector)    std::vector<int>;
%template(DoubleVector) std::vector<double>;

/* Let's just grab the original header file here */
%include "example.h"

这带来了:

问题是,如果某个名称(无效的_参数)与ocaml C接口中预定义的带有“caml_”前缀(caml_无效的_参数)的名称一致,则在编译过程中,在某些地方,前者的所有出现似乎都被后者所取代。 我用不同的名称(initialize和caml\u initialize)和不同的环境(macOS Sierra with clang或g++,ubuntu 14.10和g++)观察到了相同的问题。 这是swig或ocaml中的错误吗?
