Fails with latest IDE and Arduino

[joeinaustin]

I see some references to this that are quite old. It seemed to say this was fixed. But I just upgraded top the latest of Arduino and the IDE and they have identical issues.

(.text+0x0): multiple definition of `std::nothrow'

I have tried the 1.8.5 and the IDE rc6. Am I missing something here, or has this issue resurfaced?

Downgrading AVR boards allowed me to continue. Will there be a long term fix?

Noted that it still fails on Arduino IDE 1.8.19. VS and VSCode are also installed on the system.

The test program is an empty/new application with

#include <Arduino.STL>
using namespace std;

at the top.

Error message is (some blank lines removed)

Arduino: 1.8.19 (Windows 10), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"

See my fork that should have fixed this.
