Description
ESP crashes when Debug Level is set higher than 1 and the access point it is connected to, is forcefully stopped.
Assumptions about the cause:
In WiFiGeneric.cpp event->event_info.disconnected.reason turns 0 which causes reason2str to access system_event_reasons at an index of -1. In the current implementation of the function it is not possible to access index 0 at all.
The issue seems similar to #2334
