This is the same as the other patch, except that it is applied to the case where the QI returns an nsresult. In addition, I marked the WithError helper class as being stack-only. Depends on D7553 Differential Revision: https://phabricator.services.mozilla.com/D7554 --HG-- extra : moz-landing-system : lando
