Create a new project for a DiscoveryF4 or a Nucleo-144 767. Both of these boards has a push button on it.
The disco's button is set for external event mode, set it for External interrupt mode in the GPIO configuration tab. The nucleo already comes set for interrupt mode, do nothing.
Click into the NVIC configuration. Notice that there is no affordance to generate the interrupt support code.
This worked previously but has now regressed.
