You need to run the static analyser. The documentation about MOZ_MUST_USE_TYPE is explained there http://searchfox.org/mozilla-central/source/mfbt/Attributes.h#519-521. This is why you should always do a try run, because the static analyser *will* choke on this code. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
