是代码有数据结构在arm32平台对齐的问题，因为我们这里没有相应硬件不好测试，你可以试试这里改一下，如果OK的话可以给我们提个 PR

按照上面改了没有，还是报错
我coredump了下：

是对double 这个类型得指针地址没对齐照成的

试试这样行不行？

如果您有余力解决欢迎自己移植并贡献 PR 给 TDengine

这些代码片段 left，right 都是void* 类型，是32bit在armv7 架构下，但是在 isNull 函数下

*(uint64_t *)val 这个操作设计到对64bit的读取，这样会不会成了非对齐的数据访问了

在这个函数中 pdata 这个内存都忘了释放了
