I'm not sure correctly understood, but I think your reply is not
relevant to a problem I reported.
The above citation is about order of certificates in the chain sent in
the TLS protocol by server right?

The reported problem is about order of certificates with the same
subject DN in the repository during verifying certificate. I have server
certificates issued by older and newer CA certificate both valid of
course. GnuTLS must find the right certificate of CA from two or even
more with the same subject DN.

I tried to examine in the bug-report, that based on the order of two CA
certificates with the same subject DN IN THE REPOSITORY the GnuTLS fails
on newer or older server certificate. There was no change on server
sides or so. I changed CA cert order only on the client side repository.

Thanks for your time.
Best Regards
