Possiblly bug of cygwin1.dll

[Takashi Yano <takashi.yano@nifty.ne.jp>]

Hi,

I might find the bug of cygwin1.dll (including 3.4.x, 3.5.0 (TEST)).
The following test case (c++ code) causes handle leak.

This issue is reproducible with both g++ and clang++.
However, it does not happen in Linux environment.
So I guess this is the cygwin1.dlll bug.

I looked into this problem a bit, and found number of event handle
increases every loop.

I doubt pthread_mutex_xxx functions.

#include <future>
int func() { return 0; }
int main()
{
  for (;;) {
    std::future<int> f = std::async(std::launch::async, func);
    f.get();
  }
  return 0;
}
