Sorry, It was my fault to forget to check the docs about the version 1.0.2.
However, in the ref
https://www.openssl.org/docs/manmaster/man3/X509_NAME_oneline.html which is the
latest version docs says NULL on error.

Also,the 1.0.2 version is already corrected referring to the latest standards.

ref:
https://github.com/openssl/openssl/blob/OpenSSL_1_0_2-stable/crypto/x509v3/v3_alt.c

152:        if (X509_NAME_oneline(gen->d.dirn, oline, 256) == NULL
153:                || !X509V3_add_value("DirName", oline, &ret))
154:           return NULL;



The 1.1.0 version is corrected too.

ref:
https://github.com/openssl/openssl/blob/OpenSSL_1_1_0-stable/crypto/x509v3/v3_alt.c

103:        if (X509_NAME_oneline(gen->d.dirn, oline, 256) == NULL
104:                || !X509V3_add_value("DirName", oline, &ret))
105:           return NULL;
