 ticket: 6908
 subject: Delete sec context properly in gss_krb5_export_lucid_sec_context
 target_version: 1.9.2
 tags: pullup

 Since r21690, gss_krb5_export_lucid_sec_context() has been passing a
 union context to krb5_gss_delete_sec_context(), causing a crash as the
 krb5 routine attempts to interpret a union context structure as a krb5
 GSS context.  Call the mechglue gss_delete_sec_context instead.
