json_object_array_del_idx function has segment fault error?

[jalnanco]

I made an array to take three json_objects.
When I use json_object_array_del_idx function it has error like this

save part

        json_object *my_object = json_object_new_object();
        json_object_object_add(my_object, "EUI64", json_object_new_int64(eui64.llvalue));
        json_object_object_add(my_object, "nodeId", json_object_new_int(nodeId.lvalue)); 
        json_object_object_add(my_object, "Key", json_object_new_int(globalKey.lvalue));
        json_object_array_add(pairArray, my_object);

delete part

int targetIndex = searchPairWithEUI64(pairArray, eui64);
if(targetIndex != -1) {
    if(json_object_array_del_idx(pairArray, targetIndex, 1) == 0 ) {
        emberSerialPrintf(APP_SERIAL,"Delete Success\r\n");
    }
}

the result in delete part:
Segmentation fault (core dumped)

There's nothing obviously wrong in those few lines of code you listed but you're not providing enough information to figure out anything at all.
Where does it crash? Have you checked targetIndex vs the size of pairArray to ensure it's in range? Do you have a minimal test case that shows the problem?

I think It might be my mistake.
I should make a code and test it again.
Sorry for bother you. this is not enough explained.
Anyway, Thank you for reply

Ok, good luck finding the bug. If it turns out to be a problem in json-c, please re-open this issue.
