急求：应用UF_UI_open_part 出错原因

dchl0301

调试的时候提示说内存冲突，不解，想请大家来帮帮忙，致谢！
源代码：
int MY_open()
{
       
        UF_UI_err_t error_handler;
        char * file_name = "A.prt", err_message[] = "";
        logical use_display_file = FALSE;
        tag_t part_tag = NULL_TAG;
        int response;
        const char *message = "part open error";
        UF_PART_load_status_t part_status;

        error_handler.type = UF_UI_open_part_fun;
    error_handler.fun.open = my_error_handler;
        error_handler.fun_data.size = strlen ( message ) + 1;
    error_handler.fun_data.data = message;
       
    response = UF_UI_open_part (&error_handler, file_name, &use_display_file, &part_tag, &response, &part_status);
        UF_get_fail_message(response, err_message);
        if ( part_status.statuses != NULL )
        UF_free ( part_status.statuses );
    if ( part_status.file_names != NULL )
        UF_free_string_array ( part_status.n_parts ,part_status.file_names );

        uc6476(1);
       
   if ( part_tag==NULL_TAG )
           return 1;
   else
           return 0;
          
}
