### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Version dev-1.0.0 ### What's Wrong? BUILD_TYPE=tsan ./build.sh --be 使用clang，如上编译之后，启动的时候，会发生memcpy的递归调用，从而发生栈溢出。  原因： 在src/glibc-compatibility/memcpy/memcpy_x86_64.cpp中，自定义的memcpy调用了__builtin_memcpy，而__builtin_memcpy被编译器优化为memcpy，从而产生循环调用。  [stackoverflow相关问题](https://stackoverflow.com/questions/8503194/using-gccs-builtin-functions-in-arm) 该问题只在指定TSAN + -O0时出现，修改为-O1，__builtin_memcpy就不会优化成memcpy。 ### What You Expected? 使用TSAN + -O0进行编译，也可以顺利启动be。 ### How to Reproduce? _No response_ ### Anything Else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
