Description
初次安装SQLAdvisor费了老大劲了，终于安装成功。准备验证奇迹的时刻，在sql语句的分析中简单的sql分析执行的都没问题，但是到了一些复杂的sql时偶尔会报错，报错信息如下：
Segmentation fault (core dumped)
查看linux系统日志发现了如下内容：
kernel: sqladvisor[24453]: segfault at 0 ip 000000344da361a2 sp 00007fff68c32a90 error 4 in libc-2.14.so[344da00000+183000]
待求大神解决

Research direction
The report names no source file, test, or reproducible query. Start by reproducing the failure with the complex SQL on Linux and inspect the core dump alongside the libc and kernel details; done means the crash is isolated and a regression test demonstrates that the query no longer segfaults.
