### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version master ### What's Wrong? When building BE unit tests in LSAN+UBSAN mode, the linker reports a duplicate symbol error: ``` ld.lld: error: duplicate symbol: __lsan_ignore_object >>> defined at lsan_common.cpp.o:(__lsan_ignore_object) in archive /var/local/ldb-toolchain/tmp/gentoo/llvm/bin/../../../../lib/clang/20/lib/linux/libclang_rt.lsan-x86_64.a >>> defined at phdr_cache.cpp:113 (./be/ut_build_LSAN/./be/src/common/phdr_cache.cpp:113) >>> phdr_cache.cpp.o:(.text+0x0) in archive src/common/libCommon.a clang++: error: linker command failed with exit code 1 (use -v to see invocation) ``` ### What You Expected? BE UT should build and run successfully in LSAN+UBSAN mode without duplicate symbol errors. ### How to Reproduce? 1. Build BE with LSAN+UBSAN mode 2. Run `bash run-be-ut.sh` 3. Linker fails with duplicate symbol `__lsan_ignore_object` ### Root Cause In `be/src/common/phdr_cache.cpp`, the `__lsan_ignore_object` function is manually declared and defined: ```cpp extern "C" { #ifdef ADDRESS_SANITIZER void __lsan_ignore_object(const void*); #else void __lsan_ignore_object(const void*) {} // NOLINT #endif } ``` When building with LSAN (Leak Sanitizer) enabled, the LSAN runtime library (`libclang_rt.lsan-x86_64.a`) already provides the `__lsan_ignore_object` symbol. The manual definition in `phdr_cache.cpp` conflicts with it, causing the duplicate symbol error. Additionally, `be/src/util/debug/leak_annotations.h` only enables `ANNOTATE_LEAKING_OBJECT_PTR` when `address_sanitizer` is detected, but not when `leak_sanitizer` is detected independently. This means the existing annotation mechanism does not work properly under LSAN-only mode. ### Are you willing to submit PR? - [X] 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.
