Thanks for the int size hint. I am aware of that, I made this mistake when shrinking the code to provide a minimum example.
The software watchdog is not the problem, disabling it alltogether with ESP.wdtDisable(); does not make a difference. I tried to include yield or delay into the for loop but that does not make a difference.
My controller gets reset by the hardware watchdog a couple of seconds after the program stops doing anything apparently.
The general problem is that the crash does not occur somewhere in my code but in the waiting part in the main loop. If I add some debug output like this:
void loop() {
unsigned long currentMillis = millis();
if (currentMillis - previousMillis >= interval) {
Serial.println("Start of if");
previousMillis = currentMillis;
rt.updatePosition();
Serial.println("End of if");
}
}
I get the following output:

As you can see, the "End of if" text is still sent right before the program completely stops responding.
