WiFiManager: Exception 3 WiFiManager::getParamOut() when ConfigPortal started

Basic Infos

I try the last ESP8266 SDK with development branch and it’s falls when ConfigPortal started. How I can debug this problem? It’s important to use latest SDK =(. Thanks!

Hardware

WiFimanager Branch/Release:

  • Master
  • Development

Esp8266/Esp32:

  • ESP8266
  • ESP32

Hardware: ESP-12e, esp01, esp25

  • ESP01
  • nodemcu
  • Other

ESP Core Version: 2.4.0, staging

  • 2.3.0
  • 2.4.0
  • staging (master/dev) don’t know

Description

I try development branch with 2.5.2 SDK and it fails. I’m confuzed, cause it works with 2.0.4 version… 2.1.0, 2.2.0 also raise exceptions.

I use ~30 params in config.

@tablatronix I try to describe: in esp PROGMEM string must be used only by special fuctions: memcmp_P, strlen_P and etc.

Working with PROGMEM strings with common functions “strlen”, “memcmp”, “scanf” is dangerous (read “prohibited”).

What’s why this “operator=” can raise exception: https://github.com/tzapu/WiFiManager/blob/master/WiFiManager.cpp#L543

Look at String contructors:

String::String(const char *cstr) {  //for common strings
    init();
    if(cstr)
        copy(cstr, strlen(cstr));
}

String::String(const __FlashStringHelper *pstr) { //for PROGMEM
    init();
    *this = pstr; // see operator =
}

String & String::operator = (const __FlashStringHelper *pstr)
{
    if (pstr) copy(pstr, strlen_P((PGM_P)pstr));  //WOW strlen_P not strlen 
    else invalidate();
    return *this;
}
String & String::copy(const __FlashStringHelper *pstr, unsigned int length) {
    if (!reserve(length)) {
        invalidate();
        return *this;
    }
    setLen(length);
    strcpy_P(wbuffer(), (PGM_P)pstr);  //WOW #2 strcpy_P not strcpy
    return *this;
}

if you set DEBUG_MAX in .h file for debuglevel uint8_t _debugLevel = DEBUG_MAX;

you will get debugging for heap size in logs. I am guessing you are out of memory, and sdk uses more now ?
