Not reproduce it under centos:7 with devtoolset-9. I run the sdk_simple success.

@Renekton Could you share more information, e.g. how do you using devtoolset-9, I usually use source /opt/rh/devtoolset-9/enable to enable it globally. Or, you may upload your core file and sdk_simple and libmilvus_sdk.so, that will help me do more investigation on it.

1. I run the commad "scl enable devtoolset-9 bash " to change the version of g++;
2. CentOS Linux release 7.9.2009 (Core)

core_info.zip 4. I have some tests, It may be associated with _GLIBCXX_USE_CXX11_ABI

@matrixji maybe, it is associated with the version of libstdc++.so.6 and libc.so.6 . Could you show your version of libstdc++.so and libc.so.6？

I guess we have the same libstdc++.so

[root@b555b131cbbb ~]# ls -al /lib64/libstdc++.so.6
lrwxrwxrwx 1 root root 19 Nov 13  2020 /lib64/libstdc++.so.6 -> libstdc++.so.6.0.19
[root@b555b131cbbb ~]# md5sum /lib64/libstdc++.so.6.0.19

[root@b555b131cbbb ~]#

Have you tried compiling with -D_GLIBCXX_USE_CXX11_ABI=1?
