We sometimes hit the following assertion: ASSERTION FAILED: WebCore::SQLiteDatabaseTracker::hasTransactionInProgress() in NetworkCache::Statistics::initialize() 0x107ff3020 WTFCrash 0x1036fe3fc WebKit::NetworkCache::executeSQLCommand(WebCore::SQLiteDatabase&, WTF::String const&) 0x1036fdaaa WebKit::NetworkCache::Statistics::initialize(WTF::String const&)::$_0::operator()() const 0x1036fd6bc std::__1::__function::__func<WebKit::NetworkCache::Statistics::initialize(WTF::String const&)::$_0, std::__1::allocator<WebKit::NetworkCache::Statistics::initialize(WTF::String const&)::$_0>, void ()>::operator()() 0x107b4358a std::__1::function<void ()>::operator()() const 0x108014bb9 invocation function for block in WTF::WorkQueue::dispatch(std::__1::function<void ()>) 0x101beebfd _dispatch_call_block_and_release 0x101c0e40d _dispatch_client_callout 0x101bf50ff _dispatch_queue_drain 0x101bf46fc _dispatch_queue_invoke 0x101bf6c1f _dispatch_root_queue_drain 0x101bf66bc _dispatch_worker_thread3 0x101f308a6 _pthread_wqthread 0x101f2e0c5 start_wqthread I do have a "WebCore::SQLiteTransactionInProgressAutoCounter transactionCounter" in NetworkCache::Statistics::initialize(). My current guess is that the SQLiteDatabaseTrackerClient can get set after transactionCounter is initialized but before executeSQLCommand() is called.
