@PiliLatiesa

Description

@PiliLatiesa

The following program:

#include <future>
#include <iostream>

void Fn() {}

int main()
{
  std::future<void> Future;
  
  Future = std::async(std::launch::async, Fn);
  
  Future.get();
  
  std::cin.get();
  
  return 0;
}

compiled with:

cl Source.cpp /EHsc /O2 /MD
Compilador de optimización de C/C++ de Microsoft (R) versión 19.42.34436 para x86

Source.cpp
Microsoft (R) Incremental Linker Version 14.42.34436.0
Copyright (C) Microsoft Corporation.  All rights reserved.

/out:Source.exe
Source.obj

crashes when executed on a computer with the MSVC redistributable version 14.29.30135 installed.

Isn't this combination supposed to work?
