【22.03 LTS】asan：结合npb测试存在泄露

【环境信息】
[wd@localhost dailytest]$ uname -a
Linux localhost.localdomain 5.10.0-5.10.0.24.oe1.aarch64 #1 SMP Sun Sep 12 19:59:51 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux
【问题复现步骤】
环境变量：
```
export PATH=/home/wd/dailytest/330_asan/install/bin:$PATH
export PATH=/home/wd/codedb/dependence/openmpi/openmpi-4.0.4/bin:$PATH
export LD_LIBRARY_PATH=/home/wd/codedb/dependence/openmpi/openmpi-4.0.4/lib:$LD_LIBRARY_PATH
export ASAN_OPTIONS="handle_segv=0:halt_on_error=0:use_sigaltstack=0:detect_leaks=1"
```
1.auto-profile.c和final.c步骤：
```
cd /home/wd/codedb/c_cpp/NPB_bolt/NPB3.4.1/NPB3.4-MPI
make BT CLASS=A NPROCS=96
```
2.tree-ssa-loop-prefetch.c步骤：
```
cd /home/wd/codedb/c_cpp/NPB_cache_2/NPB3.4.1/NPB3.4-MPI
make BT CLASS=A NPROCS=96
```
【预期结果】
无asan error
