在做memcheck版本的時候，編譯過來拿到運行環境已運行，出現以下問題
./gs_guc: error while loading shared libraries: libasan.so.4: cannot open shared object file: No such file or directory
用ldd 查看gs_guc，ldd
ldd ./gs_guc
linux-vdso.so.1 => (0x00007ffc8ad73000)
libachk.so => /lib64/libachk.so (0x00007f9c01dfe000)
libasan.so.4 => not found
libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007f9c01abb000)

/lib64/ld-linux-x86-64.so.2 (0x00007f9c01cf2000)
可以看到缺乏libasan.so.4，搜索本環境上的文件
find / -name libasan.so.4 2>/dev/null
然后將文件拷貝到/var/chroot/usr/local/core/app/lib/
接着運行，出現以下錯誤
==10929==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.
執行echo $LD_PRELOAD
export LD_PRELOAD=/var/chroot/usr/local/core/app/lib/libasan.so.4
則可執行成功
