Use attachInterrupt() inside a template class

[lebuni]

Hardware:

Board: ESP32-WROOM-32
Core Installation version: 1.0.6
IDE name: Arduino IDE
Flash Frequency: 80Mhz
PSRAM enabled: no
Upload Speed: 256000
Computer OS: Windows 10

Description:

I wanna attach an external interrupt from inside a template class. Used like in the code below, the ESP32 crashes immediatly. Outside the template class attachInterrupt() works fine. From inside the template class I can attach that ISR via gpio_isr_handler_add() without problems.
Is there a way to use attachInterupt() inside a template class?

Sketch:

#include <Arduino.h>
#include <Preferences.h>
Preferences preferences;

template <int pin>
class myTemplateClass {
  
    static void IRAM_ATTR externalISR() {
      //do stuff
    }

   public:

      myTemplateClass() {}
      
      void begin() {
        attachInterrupt(digitalPinToInterrupt(pin), externalISR, RISING);
      }
};

myTemplateClass<14> myObj;

void setup() {
  Serial.begin(500000);
  myObj.begin();  
}

void loop() {
  preferences.begin("config");
  preferences.clear();
  preferences.end();
}

It seems to be a bug in the gcc compiler, which already exists as an issue here: espressif/esp-idf#4542
