Attachment: event_tracer_destructor.patch

/home/icecold/mozilla-central/xpcom/base/VisualEventTracer.cpp:646:1: error: static_assert failed "Reference-counted class VisualEventTracer should not have a public destructor. Try to make this class's destructor non-public. If that is really not possible, you can whitelist this class by providing a HasDangerousPublicDestructor specialization for it."
