MySQL5.6.35的bug

有一个系统，当在应用层面开启Job的时候，数据库就会宕机，Job里面是往一个表里面插入一些数据。错误日志如下：
      2019-11-11 15:56:26 114028 [Note] /home/mysql/bin/mysqld: ready for connections.

Version: ‘5.6.35-log’ socket: ‘/tmp/mysql.sock’ port: 3306 Source distribution  
**terminate called after throwing an instance of ‘std::out\_of\_range’  
what(): vector::\_M\_range\_check  
07:56:53 UTC - mysqld got signal 6 ;**  
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.  
We will try our best to scrape up some info that will hopefully help  
diagnose the problem, but since we have already crashed,  
something is definitely wrong and this may fail.

key\_buffer\_size=8388608  
read\_buffer\_size=1048576  
max\_used\_connections=24  
max\_threads=8000  
thread\_count=24  
connection\_count=24  
It is possible that mysqld could use up to  
key\_buffer\_size + (read\_buffer\_size + sort\_buffer\_size)\*max\_threads = 24686379 K bytes of memory  
Hope that’s ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went  
terribly wrong…
