Sorry, please try the following with the Demo app from the current tip:
void MainAppWindow::closeButtonPressed()
{
if(taskbarIcon)
taskbarIcon = nullptr;
else
taskbarIcon = new DemoTaskbarComponent();
//JUCEApplication::getInstance()->systemRequestedQuit();
}
Then click the app close button a few times.
For me it crashes in frameChanged of juce_mac_SystemTrayIcon.cpp
The Xcode console output shows:
