vins里增加线特征node时，启动launch,新增的node总是挂掉，会有哪些原因呢

[小卢]

[linefeature_tracker-4] process has died [pid 36717, exit code -11
我在VINS_MONO中想要新增加一个线特征提取节点，在写好的代码后，代码能编译通过，并且启动launch时可以看见
process [linefeature_tracker-4]: started with pid [36717]
但是后续启动完成就会出现
[linefeature_tracker-4] process has died
我想了解一下这部分可能会在哪里出现问题，目前有点不知道该怎么去定位到问题， 感谢大家。下面是报错信息。（ubuntu18.04 + ROS）
