Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/1325

I combined two working examples, WiFiManager and AsyncElegantOTA, producing one app that panic’s the core. Is there a combability issue or my coding. Two great features should play well together. Others have verified the same problem.

I get two stack dump:

Basic Infos

Hardware

WiFimanager Branch/Release: Master V0.16(Latest)

Esp8266/Esp32:

Hardware: NodeMCU 1.0 (ESP-12E)

Core Version: ?

Description

Panic core when trying to upload a new .bin image. Works fine when AsyncElegantOTA is not included.

Settings in IDE

Module: NodeMcu

Additional libraries:
bbx10/DNSServer@^1.1.0
ottowinter/ESPAsyncWebServer-esphome @ ^2.1.0
tzapu/WiFiManager@^0.16.0
ayushsharma82/AsyncElegantOTA@^2.2.6

AsyncWebServer server(80);

  Serial.println(WiFi.localIP());

  server.on("/", HTTP_GET, [](AsyncWebServerRequest *request) {
    request->send(200, "text/plain", "Hi! I am ESP8266.");
  });

  AsyncElegantOTA.begin(&server);    // Start ElegantOTA
  server.begin();
  Serial.println("HTTP server started");
}

void loop(void) {
  AsyncElegantOTA.loop();
}

none of that trace looks like wm, I assume this is something you are doing , like lost memory pointer or overflow, or a bug in esp
