Looking at ipa-join.c patch, I noticed one thing:

I think you also need to bump XMLRPC_CXPSIZE() to gssapi_delegation:

diff --git a/ipa-client/ipa-join.c b/ipa-client/ipa-join.c

     clientparms.transport = "curl";
     clientparms.transportparmsP = (struct xmlrpc_xportparms *)
             curlXportParmsP;
