WiFiClientSecureBearSSL.h & compiler issue - follow up

Hi all,

I'm following up again about my issue. Could you please give me time to reply before closing issues?

I can clearly reproduce the behavior. I have started from scratch, removing anything related to Arduino.

Since I can reproduce the issue, and the library conflict looks due to something shipped with the software, I'd appreciate if you could take a look . I understand I can potentially go around a delete some files to avoid the conflict, however I'd be better such libraries don't hit each other from a default installation.. I really believe I'm not doing something wrong, I think the conflict is between the code shipped with the board and with arduino ide. Am I wrong? As you see form the error, the libraries are not from file system positions of the additional libraries.

Steps to reproduce:

1) install arduino ide 1.8.9 (latest) 2) From the board manager, add https://arduino.esp8266.com/stable/package_esp8266com_index.json 3) Add the new board, esp8266, choosing the latest version 4) select the wemos d1 mini board 5) add the libraries for Adafruit_BMP085.h, NTPClient.h and PubSubClient.h. All other libraries are installed by default, and can't be removed from the GUI. 6) Run the following code:

#include <Adafruit_BMP085.h>
#include <DNSServer.h>
#include <ESP8266WiFi.h>
#include <EEPROM.h>
#include <ESP8266WebServer.h>
#include <ESP8266HTTPClient.h>
#include <ESP8266httpUpdate.h>
#include <NTPClient.h>
#include <PubSubClient.h>
#include <stdlib.h>
#include <WiFiClient.h>
#include <WiFiUdp.h>
#include <Wire.h>

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

With this code I still get the following error:

Arduino: 1.8.9 (Linux), Board: "LOLIN(WEMOS) D1 R2 & mini, 80 MHz, Flash, Disabled, All SSL ciphers (most compatible), 4M (no SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 921600"
