一、缺陷信息
【环境信息】
软件信息

OS版本及分支信息:openEuler-22.03-LTS-SP3
内核信息:5.10.0-179.0.0.93.oe2203sp3.aarch64
发现问题的组件版本信息：gcc-10.3.1-45.oe2203sp3.aarch64

Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/aarch64-linux-gnu/10.3.1/lto-wrapper
Target: aarch64-linux-gnu
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,fortran,objc,obj-c++,lto --enable-plugin --enable-initfini-array --disable-libgcj --with-isl --without-cloog --enable-gnu-indirect-function --build=aarch64-linux-gnu --with-stage1-ldflags=' -Wl,-z,relro,-z,now' --with-boot-ldflags=' -Wl,-z,relro,-z,now' --disable-bootstrap --with-multilib-list=lp64 --enable-bolt

【问题复现步骤】
1.配置工具链：

export PATH=/usr/bin:$PATH
export LD_LIBRARY_PATH=/usr/lib64:$LD_LIBRARY_PATH

2.源码私下分享
3.执行以下命令进行编译

export CC="gcc -O2 -fifcvt-allow-complicated-cmps --param=ifcvt-allow-register-renaming=2"
export CXX="g++ -O2 -fifcvt-allow-complicated-cmps --param=ifcvt-allow-register-renaming=2"
tar -xf llvm-12.tar.gz
cd llvm-project
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=/path/install -DCMAKE_BUILD_TYPE=Release  -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;libcxx;libcxxabi;libunwind;lldb;compiler-rt;lld;polly" ../llvm
sed -i '86,95s/^/#/g' projects/libcxx/src/cmake_install.cmake
make -j96
