Description

consider this call chain:
nsObserverService::NotifyObservers
nsObserverService::EnumerateObservers
nsObserverService::GetObserverList
nsObserverList::GetObserverList

139     ObserverListEnumerator * enumerator= new
ObserverListEnumerator(mObserverList);
140     NS_IF_ADDREF(enumerator);
141     *anEnumerator = enumerator;
142     return NS_OK;

let new fail.
anEnumerator = 0
return NS_OK

this bubbles to 
199     rv = EnumerateObservers( aTopic, getter_AddRefs(observers) );
200     if ( NS_FAILED( rv ) )
false, so skip return
201         return rv;

203     while( NS_SUCCEEDED(observers->HasMoreElements(&loop)) && loop) 
null, so crash.
