I have performed such test last week - yes, it is not OpenCA problem, it is
OpenSSL issue. Openssl mailing list haven't answered me about 64 char

Unfortunately I can't ask my client to shorten it's organization name,
because by the rule I must include in O= exact name from organization
registration documents.
