在做memcheck版本的时候，编译过来拿到运行环境已运行，出现以下问题
./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)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f9c018b7000)
libssl.so.1.1 => /var/chroot/usr/local/core/app/lib/libssl.so.1.1 (0x00007f9c01628000)
libcrypto.so.1.1 => /var/chroot/usr/local/core/app/lib/libcrypto.so.1.1 (0x00007f9c01168000)
librt.so.1 => /lib64/librt.so.1 (0x00007f9c00f60000)
libz.so.1 => /var/chroot/usr/local/core/app/lib/libz.so.1 (0x00007f9c00d49000)
libstdc++.so.6 => /var/chroot/usr/local/core/app/lib/libstdc++.so.6 (0x00007f9c009c6000)
libm.so.6 => /lib64/libm.so.6 (0x00007f9c006c4000)
libgcc_s.so.1 => /var/chroot/usr/local/core/app/lib/libgcc_s.so.1 (0x00007f9c004ac000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f9c00290000)
libc.so.6 => /lib64/libc.so.6 (0x00007f9bffebf000)
libfreebl3.so => /lib64/libfreebl3.so (0x00007f9bffcbc000)
/lib64/ld-linux-x86-64.so.2 (0x00007f9c01cf2000)
可以看到缺乏libasan.so.4，搜索本环境上的文件
find / -name libasan.so.4 2>/dev/null
然后将文件拷贝到/var/chroot/usr/local/core/app/lib/
接着运行，出现以下错误
==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.
执行echo $LD_PRELOAD
export LD_PRELOAD=/var/chroot/usr/local/core/app/lib/libasan.so.4
则可执行成功
