Come across a bug in the Visual Studio 11 (preview).

#include <future>

int main(int argc, char* argv[]) {
  for (auto i = 0L; i < 1000000; ++i) {
    auto f = std::async([](){ return 0; });
    f.get();
  }
  return 0;
}

This code consistently crashes (and doesn’t throw). When decreasing a number of iteration, at some point to stops crashing.

The compiler cl.exe 17.00.40825.2, IDE 11.0.40825.2 PREREL. Posted on Stack Overflow. They say, likely it is the bug.

Where to file a bug to VS?
