ESP-01 keeps restarting with INIT_CHARACHTERISTIC_VAL

[matrixall]

I'm using the ESPhapled2866 example with no modification, Everything works fine. However, when I add the initial value code to my sketch I still get the light button active and once I press it the ESP keeps restarting:
Here is the code I modified:

if(hapservice){
 Serial.println("notify hap"); 
 //getting on/off characteristic
 homekit_characteristic_t * ch= homekit_service_characteristic_by_type(hapservice, HOMEKIT_CHARACTERISTIC_ON);
 INIT_CHARACHTERISTIC_VAL(bool,ch,false);
 if(ch){
     Serial.println("found characteristic"); 
     if(ch->value.bool_value!=val){  //wil notify only if different
       ch->value.bool_value=val;
       homekit_characteristic_notify(ch,ch->value);
     }
 }
}

Here is the serial output:

closing the issue as it can be achieved with
hap_setinitial_characteristic_bool_value(hapservice,HOMEKIT_CHARACTERISTIC_ON,false);
