The ESP32 IDE compiler is intolerant

But if I remove the return statement (which is not a good practice), the code continues to work on all my boards except on the ESP 32 where it crashes

Interesting. For me, a function with return type int, and no return statement:

• Compiles with a warning when building for Arduino Uno R3
• Fails to compile when building for ESP32 Dev board

I'm using Arduino IDE 1.8.13. I've not tried running the code on either board.
