krb5_cc_cache_match() searches all ccache collections for a ccache that has credentials for a given principal name. This includes MEMORY ccaches, which means it can find the same ccache as is referenced by a GSS cred handle given to gss_store_cred(), which means that gss_store_cred() can fail. For now we work around this by including a private variant of krb5_cc_cache_match() that only searches the default ccache, not all collections. Eventually we should ensure that krb5_cc_default() also searches all collection-type (other than MEMORY) ccaches for a default credential, then we can go back to using krb5_cc_cache_match() (though we'll need to make sure that MEMORY is searched last or not at all).
