Memory Leak in WiFi.begin() when network is out of range

[intakenick]

When connecting to client, via wifi.begin(), I receive a guru meditation error but only when in one room of my house. When situated closer to the router, it connects fine. When completely out of range, it times out and fails to connect as expected. It seems that there is a memory issue in one of the core libraries. Currently using a Node32s. See code and dump below:

`bool WiFiModem::ConnectClient() { _logger->SendMessage("WiFi Connecting!"); _isClientConnected = _wifi.status() == WL_CONNECTED; if (_isClientInitialized) { WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0); //disable brownout detector _logger->SendMessage("Starting connection..."); _logger->SendMessage(_clientSSID); _logger->SendMessage(_clientPassword); if (!_isClientConnected) { _wifi.disconnect(true); _wifi.enableSTA(true); _logger->SendMessage("WiFi EnableSTA"); _logger->SendMessage("WiFi Begin"); const char ssid = _clientSSID.c_str(); const char password = _clientPassword.c_str(); _wifi.persistent(false); _wifi.setSleep(false); delay(10); _wifi.begin(ssid, password); _logger->SendMessage("WiFi SetSleep");

        long start=millis();
        _display->ClearDisplay();
        _display->DisplayLargeMessage(" WAIT");
        while (_wifi.status() != WL_CONNECTED) {
            //_logger->SendMessage("Waiting....."); 
            delay(200);   
            if(millis()%400<200){
                led.setPixelColor(0,led.Color(0,0,100));
                led.show();
            }      
            else{
                led.clear();
                led.show();
            }      
            if(abs(millis()-start)>10000){
                _logger->SendMessage("WiFi Failed");  
                led.clear();
                led.show(); 
                break;            
            }
            if(digitalRead(BUTTON)){
                _display->ClearDisplay();
                _isClientConnected=false;
                led.clear();
                led.show();
                return 1;
            }
        }
        _logger->SendMessage("WiFi Connected...");
        //delay(50);
        led.clear();
        led.show();
        _display->ClearDisplay();            

    } else {
        _logger->SendMessage("WiFi already connected");
    }
    if (_wifi.status() == WL_CONNECTED) {
        _isClientConnected = true;
        _logger->SendMessage("Client IP Address: " + _wifi.localIP().toString());
    } else {
        _isClientConnected = false;
    }

} else {
    _logger->SendMessage("WiFi NOT initialized!");
}`

I receive the following error sometime while waiting in the while (_wifi.status() != WL_CONNECTED) loop (decoded):

Also seems you decoded the backtrace on Core0 instead of Core1 where the issue shows. Using interrupts? Code for it?

[intakenick]

Both errors are decoded above, each start with "decoding stack results," I messed up the code paste formatting somehow. There are no interrupts, just the code above. There is some prior use of spiffs to store two HTML files but those are uslnused here.

Also tried adding delays to the loop but no luck. Any idea why this might work both in and out of range but not in the middle?
