<div>
<pre>Right after the main resource load is converted to a download, the web process deletes the ResourceLoader which sends the RemoveLoadIdentifier to the network process and the load is aborted. Sometimes it happens that NetworkResourceLoader::abort() is called while the NetworkLoad is still deciding the destination of the download. In such case, NetworkResourceLoader::didConvertToDownload() has already been called, but not NetworkResourceLoader::didBecomeDownload(). In NetworkResourceLoader::abort() we already handle the case of having a NetworkLoad after NetworkResourceLoader::didConvertToDownload() has been called, to avoid canceling the load in such case, however cleanup() is always called unconditionally and the NetworkLoad is deleted before NetworkResourceLoader::didBecomeDownload() is called. When the NetworkLoad is destroyed the NetworkDataTask client becomes nullptr, leaving it in a state where both the client is nullptr and the download hasn't been created yet. Tha
