Research direction
Start by reproducing the crash with the reported SELECT statement and compare the parser log stages, especially the WHERE comparison that is reported as a join condition. Trace SQLAdvisor's SQL parsing and join-condition handling to determine why this input reaches that path. Done means the query parses without a segmentation fault and no longer produces an incorrect join-condition interpretation.

Description
select * from rocket_release where end_time>start_time order by id desc
日志:
2020-06-03 15:38:00 7482 [Note] 第1步: 对SQL解析优化之后得到的SQL:select * AS * from nasa.rocket_release where (end_time > start_time) order by id desc
2020-06-03 15:38:00 7482 [Note] 第2步:开始解析join on条件:end_time=start_time
Segmentation fault
没看实现代码,但是估计是识别解析的逻辑有问题,不知道这里为什么会有join on条件
