Udp.destinationIP() crashes the ESP8266 every time it's used when not connected to UDP

@tonton81 no Basic info, no IDE Settings, no example sketch. You ignored the entire issue template, which exists for a reason.
Which core version? Try with latest git, and build with lwip2 (option in menu).

[tonton81]

latest git version, 1.8.3 IDE, lwip2

@d-a-v maybe similar to the availableForWrite() crash?

indeed, i was in a middle of a project going through the library functions one at a time, i guess i just stumbled onto them :)

@tonton81 Created #4036 to fix this.
