struct DV_COMMON_EXPORT product_config {


    int detect_delay_ms = 0;

    int detect_count_oneshot = 1;

    // yuv420p",rgb888
    std::string rpicam_pixel_type = "yuv420p";

    int tmp =44;
};

调试时发现从第一个字符串往后，字段都没有正常初始化

程序会在后面的逻辑中，崩溃在使用 rpicam_pixel_type 这个字段的时候,用 asan 看了是由于这个错误的字符串被认为超过 10 个 T 导致崩溃 随便把它赋值给其他变量就会崩溃

没有思路，有什么方式进一进定位吗
