> [wgt-backend/src/wgt/step/encryption/step_encrypt_resources.cc:175]: (error) Resource leak: input
> [wgt-backend/src/wgt/step/encryption/step_encrypt_resources.cc:251]: (error) Deallocating a deallocated pointer: output
> [wgt-backend/src/wgt/extension_config_parser.cc:27]: (performance) Variable 'config_xml_' is assigned in constructor body. Consider performing initialization in initialization list.
