I got random crash in my project was able to narrow down some until captive portal
I used sample CaptivePortal.ino where I just added Serial.begin(9600); in setup
I use nodemcu 1.0 and latest staging and just connect an android tablet to the AP and wait watching serial monitor, even not touching the tablet.
after 10min or 1h, it depend, I have some exceptions - so I have activated DEBUG and here one output
