it causes access violation because you give
X509_NAME_ENTRY_create_by_NID() a pointer to an invalid X509_NAME_ENTRY.
pX509NameEntry must be NULL or must point to a valid X509_NAME_ENTRY.
you could do it:
1.
X509_NAME_ENTRY *pX509MameEntry = NULL;
X509_NAME *pX509Name = X509_NAME_new();
/* Setup Country */
X509_NAME_ENTRY_create_by_NID(&pX509NameEntry, NID_countryName,
V_ASN1_PRINTABLESTRING, (unsigned char *) "DK", 2);
X509_NAME_add_entry(pX509Name, pX509NameEntry, 1, 1);
X509_NAME_ENTRY_free(pX509NameEntry);
pX509NameEntry = NULL;
/* Setup Organisation */
X509_NAME_ENTRY_create_by_NID(&pX509NameEntry,
NID_organizationName,V_ASN1_PRINTABLESTRING,
(unsigned char *) "ACME", 4);
2.
X509_NAME_ENTRY *pX509MameEntry = NULL;
X509_NAME *pX509Name = X509_NAME_new();
/* Setup Country */
X509_NAME_ENTRY_create_by_NID(&pX509NameEntry, NID_countryName,
V_ASN1_PRINTABLESTRING, (unsigned char *) "DK", 2);
X509_NAME_add_entry(pX509Name, pX509NameEntry, 1, 1);
/* Setup Organisation */
X509_NAME_ENTRY_create_by_NID(&pX509NameEntry,
NID_organizationName,V_ASN1_PRINTABLESTRING,
(unsigned char *) "ACME", 4);
