One of our tests also provokes a failure by selecting incompatible versions

curl_easy_perform failed: `SSL connect error'
Error: received handshake message out of context
With the latest version, the two lines are repeated several times (and the
test now fails).
Can you try with only changing libcurl OR gnutls to see which change that
introduces the problem?
My guess right now is that there must have been some incompatible (!)
protocol change in gnutls with itself (!?) or a significant change in how
libcurl uses gnutls (i.e. change of supported ciphers, certificate checking,
etc.).
I know GnuTLS has changed default crypto backend which probably implies some
amount of changes. libcurl has not changed the GnuTLS-layer code in any
significant way in a long time AFAICS. Although I don't think that a bug
necessarily needs a significant change to occur...
I've not seen or heard anyone else report about similar problems with
libcurl+gnutls...
