Why does json_decref cause a crash on Windows?

Question

C++ / C#

I use the Jansson library downloaded from off site. The problem occurs only on Windows, the same sections of code on Linux work flawlessly.

json_t *root = /* some code */

json_t *jdata, *jobj;

jdata = json_array_get(json_cfg.root, section);
jobj = json_object_get(jdata, subsection);

    for (size_t i = 0; i < sz_p; i++) {
        json_t *jsub_obj = json_object_get(jobj, params[i].name);
       /* some code */
        json_decref(jsub_obj); //<<-- нормально работает на Linux && Windows
    }
json_decref(jobj);  //<<--- WIN32:  аварийный останов core dumped
json_decref(jdata); //<<----- WIN32: аварийный останов core dumped

json_decref(root); //<<--------WIN32: аварийный останов core dumped

Can I replace with free () or not, otherwise it does not cause errors?
