This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

出现的原因是 一开始我是用了 5.8 ，然后数据目录存了一些数据，我换成5,7的时候 没有把数据删掉，再重新启动的时候，数据目录还是指向原来的数据，版本的数据格式不一样， 清空 数据目录的数据，便可以启动了
